  1.  Introduction

  1.1.  Purpose

  The GNU/Linux OS has evolved from its origins in hackerdom to a full
  blown UNIX, capable of rivaling any commercial UNIX.  It now provides
  an inexpensive base to build a great workstation.  It has shed its
  hardware dependencies, having been ported to DEC Alphas, Sparcs,
  PowerPCs, and many others.  This potential speed boost along with its
  networking support will make it great for workstation clusters.  As a
  workstation it allows for all sorts of research and development,
  including artificial intelligence and artificial life.

  The purpose of this Howto is to provide a source to find out about
  various software packages, code libraries, and anything else that will
  help someone get started working with (and find resources for)
  artificial intelligence, artificial life, etc.  All done with
  GNU/Linux specifically in mind.

  1.2.  What's New

     I chopped the Agents section into two sub-sections, one for ``''
     and one for ``''. I play it a bit fast and loose in my deciding
     what goes into each category, but it is an improvement.

     MIA found! ``'' the cellular automata programming system.  Fixed
     many bad links and cleaned out missing projects.

     and ``''.

     Updated information for some entries including ``'', ``'', ``'',
     ``'', ``'', ``'', ``'', ``'' and others.

     I also changed the MIA section to ``'' which now groups into
     subsections entries with bad links that I can't find replacements
     for and long dead projects.

  В·  v2.2 -

     Fixed a some bad links and was forced to move a few entries into

  2.  Traditional Artificial Intelligence

  Traditional AI is based around the ideas of logic, rule systems,
  linguistics, and the concept of rationality.  At its roots are
  programming languages such as Lisp and Prolog.  Expert systems are the
  largest successful example of this paradigm.  An expert system
  consists of a detailed knowledge base and a complex rule system to
  utilize it.  Such systems have been used for such things as medical
  diagnosis support and credit checking systems.

  2.1.  AI class/code libraries

  These are libraries of code or classes for use in programming within
  the artificial intelligence field.  They are not meant as stand alone
  applications, but rather as tools for building your own applications.

        ACL2 (A Computational Logic for Applicative Common Lisp) is a
        theorem prover for industrial applications. It is both a

     AI Search II

        В·  WEB site:

        Basically, the library offers the programmer a set of search
        algorithms that may be used to solve all kind of different
        problems. The idea is that when developing problem solving
        software the programmer should be able to concentrate on the
        representation of the problem to be solved and should not need
        to bother with the implementation of the search algorithm that
        will be used to actually conduct the search. This idea has been
        realized by the implementation of a set of search classes that
        may be incorporated in other software through C++'s features of
        derivation and inheritance.  The following search algorithms
        have been implemented:

        В·  depth-first tree and graph search.

        В·  breadth-first tree and graph search.

        В·  uniform-cost tree and graph search.

        В·  best-first search.

        В·  bidirectional depth-first tree and graph search.

        В·  bidirectional breadth-first tree and graph search.

        В·  AND/OR depth tree search.

        В·  AND/OR breadth tree search.

        LK is an implementation of the Lin-Kernighan heuristic for the
        Traveling Salesman Problem and for the minimum weight perfect
        matching problem. It is tuned for 2-d geometric instances, and
        has been applied to certain instances with up to a million
        cities. Also included are instance generators and Perl scripts
        for munging TSPLIB instances.

        This implementation introduces ``efficient cluster

        Logfun is a library of logic functors. A logic functor is a
        function that can be applied to zero, one or several logics so
        as to produce a new logic as a combination of argument logics.
        Each argument logic can itself be built by combination of logic
        functors. The signature of a logic is made of a parser and a
        printer of formulas, logical operations such as a theorem prover
        for entailment between formulas, and more specific operations
        required by Logical Information Systems (LIS). Logic functors
        can be concrete domains like integers, strings, or algebraic
        combinators like product or sum of logics.

        Logic functors are coded as Objective Caml modules. A logic
        semantics is associated to each of these logic functors. This
        enables to define properties of logics like the consistency and
        completeness of the entailment prover, and to prove under which
        conditions a generated entailement prover satisfies these
        properties given the properties of argument logics.

        * Note: Loom has been succeeded by ``''.

        Loom is a language and environment for constructing intelligent
        applications. The heart of Loom is a knowledge representation
        system that is used to provide deductive support for the
        declarative portion of the Loom language. Declarative knowledge
        in Loom consists of definitions, rules, facts, and default
        rules. A deductive engine called a classifier utilizes forward-
        chaining, semantic unification and object-oriented truth
        maintainance technologies in order to compile the declarative
        knowledge into a network designed to efficiently support on-line
        deductive query processing.

        The Loom system implements a logic-based pattern matcher that
        drives a production rule facility and a pattern-directed method
        dispatching facility that supports the definition of object-
        oriented methods. The high degree of integration between Loom's
        declarative and procedural components permits programmers to
        utilize logic programming, production rule, and object-oriented
        programming paradigms in a single application. Loom can also be
        used as a deductive layer that overlays an ordinary CLOS
        network. In this mode, users can obtain many of the benefits of
        using Loom without impacting the function or performance of
        their CLOS-based applications.

        PowerLoom is the successor to the ``'' knowledge representation
        system. It provides a language and environment for constructing
        intelligent, knowledge-based applications. PowerLoom uses a
        fully expressive, logic-based representation language (a variant
        of KIF). It uses a natural deduction inference engine that
        combines forward and backward chaining to derive what logically
        follows from the facts and rules asserted in the knowledge base.
        While PowerLoom is not a description logic, it does have a
        description classifier which uses technology derived from the
        Loom classifier to classify descriptions expressed in full first
        order predicate calculus (see paper). PowerLoom uses modules as
        a structuring device for knowledge bases, and ultra-lightweight
        worlds to support hypothetical reasoning.

        To implement PowerLoom we developed a new programming language
        called ``'', which is a Strongly Typed, Lisp-like LAnguage that
        can be translated into Lisp, C++ and Java. PowerLoom is written
        in STELLA and therefore available in Common-Lisp, C++ and Java

        В·  Do both forward-chaining (data driven) and backward-chaining
           (goal directed) inferencing.

           В·  Pyke may be embedded into any python program.

        В·  Automatically generate python programs by assembling
           individual python functions into complete call graphs.

           В·  This is done through a unique design where the individual
              python functions are attached to backward-chaining rules.

           В·  Unlike other approaches to code reuse (e.g. Zope adapters
              and generic functions), this allows the inference engine
              to ensure that all of the function's requirements are
              completely satisfied, by examining the entire call graph
              down to the leaves, before any of the functions are

        Screamer is an extension of Common Lisp that adds support for
        nondeterministic programming. Screamer consists of two levels.
        The basic nondeterministic level adds support for backtracking
        and undoable side effects.  On top of this nondeterministic
        substrate, Screamer provides a comprehensive constraint
        programming language in which one can formulate and solve mixed
        systems of numeric and symbolic constraints. Together, these two
        levels augment Common Lisp with practically all of the
        functionality of both Prolog and constraint logic programming
        languages such as CHiP and CLP(R).  Furthermore, Screamer is
        fully integrated with Common Lisp. Screamer programs can coexist

        The machine learning toolbox's focus is on large scale kernel
        methods and especially on Support Vector Machines (SVM) [1]. It
        provides a generic SVM object interfacing to several different
        SVM implementations, among them the state of the art LibSVM [2]
        and SVMLight [3]. Each of the SVMs can be combined with a
        variety of kernels. The toolbox not only provides efficient
        implementations of the most common kernels, like the Linear,
        Polynomial, Gaussian and Sigmoid Kernel but also comes with a
        number of recent string kernels as e.g.  the Locality Improved
        [4], Fischer [5], TOP [6], Spectrum [7], Weighted Degree Kernel
        (with shifts) [8] [9] [10]. For the latter the efficient LINADD
        [10] optimizations are implemented. Also SHOGUN offers the
        freedom of working with custom pre-computed kernels. One of its
        key features is the combined kernel which can be constructed by
        a weighted linear combination of a number of sub-kernels, each
        of which not necessarily working on the same domain. An optimal
        sub-kernel weighting can be learned using Multiple Kernel
        Learning [11] [12] [16]. Currently SVM 2-class classification
        and regression problems can be dealt with.  However SHOGUN also
        implements a number of linear methods like Linear Discriminant
        Analysis (LDA), Linear Programming Machine (LPM), (Kernel)
        Perceptrons and features algorithms to train hidden markov
        models. The input feature-objects can be dense, sparse or
        strings and of type int/short/double/char and can be converted
        into different feature types. Chains of preprocessors (e.g.
        substracting the mean) can be attached to each feature object
        allowing for on-the-fly pre-processing.

        SHOGUN is implemented in C++ and interfaces to Matlab(tm), R,
        Octave and Python.

     ASA - Adaptive Simulated Annealing

        В·  FTP site:

        ASA (Adaptive Simulated Annealing) is a powerful global
        optimization C-code algorithm especially useful for nonlinear
        and/or stochastic systems.

        ASA is developed to statistically find the best global fit of a
        nonlinear non-convex cost-function over a D-dimensional space.
        This algorithm permits an annealing schedule for 'temperature' T
        decreasing exponentially in annealing-time k, T = T_0 exp(-c
        k^1/D).  The introduction of re-annealing also permits
        adaptation to changing sensitivities in the multi-dimensional
        parameter-space. This annealing schedule is faster than fast
        Cauchy annealing, where T = T_0/k, and much faster than
        Boltzmann annealing, where T = T_0/ln k.

        CLIPS is a productive development and delivery expert system
        tool which provides a complete environment for the construction
        of rule and/or object based expert systems.

        CLIPS provides a cohesive tool for handling a wide variety of
        knowledge with support for three different programming
        paradigms: rule-based, object-oriented and procedural.  Rule-
        based programming allows knowledge to be represented as
        heuristics, or "rules of thumb," which specify a set of actions
        to be performed for a given situation. Object-oriented
        programming allows complex systems to be modeled as modular
        components (which can be easily reused to model other systems or
        to create new components).  The procedural programming
        capabilities provided by CLIPS are similar to capabilities found
        in languages such as C, Pascal, Ada, and LISP.

        The E Equational Theorem Prover is a purely equational theorem
        prover.  The core proof procedure operates on formulas in clause
        normal form, using a calculus that combines superposition (with
        selection of negative literals) and rewriting. No special rules
        for non-equational literals have been implemented, i.e.,
        resolution is simulated via paramodulation and equality
        resolution. The basic calculus is extended with rules for AC
        redundancy elemination, some contextual simplification, and
        pseudo-splitting. The latest version of E also supports
        simultaneous paramodulation, either for all inferences or for
        selected inferences.

        E is based on the DISCOUNT-loop variant of the given-clause
        algorithm, i.e. a strict separation of active and passive facts.
        Proof search in E is primarily controlled by a literal selection
        strategy, a clause evaluation heuristic, and a simplification
        ordering. The prover supports a large number of preprogrammed
        literal selection strategies, many of which are only
        experimental. Clause evaluation heuristics can be constructed on
        the fly by combining various parameterized primitive evaluation
        functions, or can be selected from a set of predefined
        heuristics. Supported term orderings are several parameterized
        instances of Knuth-Bendix-Ordering (KBO) and Lexicographic Path
        Ordering (LPO).

        extended genetic algorithm that allows fast dynamic adaptation
        of the genetic coding through population analysis. The Unit-
        Cluster Model is an approach to the construction of modular
        feedforward networks with a ''backbone'' structure.

        nn is a high-level neural network specification language. The

        recurrent models can and have been implemented, e.g. Hopfield
        nets, Jordan/Elman nets, etc.  In nn, it is easy to change
        network dynamics. The nn compiler can generate C code or
        executable programs (so there must be a C compiler available),
        with a powerful command line interface (but everything may also
        be controlled via the graphical interface, xnn). It is possible
        for the user to write C routines that can be called from inside
        the nn specification, and to use the nn specification as a
        function that is called from a C program. Please note that no
        programming is necessary in order to use the network models that
        come with the system (`netpack').

        xnn is a graphical front end to networks generated by the nn
        compiler, and to the compiler itself. The xnn graphical
        interface is intuitive and easy to use for beginners, yet
        powerful, with many possibilities for visualizing network data.

        As the field of Connectionist modeling has grown, so has the
        need for a comprehensive simulation environment for the
        development and testing of Connectionist models. Our goal in
        developing PDP++ has been to integrate several powerful software
        development and user interface tools into a general purpose
        simulation environment that is both user friendly and user
        extensible. The simulator is built in the C++ programming
        language, and incorporates a state of the art script interpreter
        with the full expressive power of C++. The graphical user
        interface is built with the Interviews toolkit, and allows full
        access to the data structures and processing modules out of
        which the simulator is built. We have constructed several useful
        graphical modules for easy interaction with the structure and
        the contents of neural networks, and we've made it possible to
        change and adapt many things. At the programming level, we have
        set things up in such a way as to make user extensions as
        painless as possible. The programmer creates new C++ objects,
        which might be new kinds of units or new kinds of processes;

        can then be accessed and used like any other.

  5.  Alife & Complex Systems

  Alife takes yet another approach to exploring the mysteries of
  intelligence.  It has many aspects similar to EC and Connectionism,
  but takes these ideas and gives them a meta-level twist. Alife
  emphasizes the development of intelligence through emergent behavior
  of complex adaptive systems.  Alife stresses the social or group based
  aspects of intelligence. It seeks to understand life and survival. By
  studying the behaviors of groups of 'beings' Alife seeks to discover
  the way intelligence or higher order activity emerges from seemingly
  simple individuals. Cellular Automata and Conway's Game of Life are
  probably the most commonly known applications of this field. Complex
  Systems (abbreviated CS) are very similar to alife in the way the are
  approached, just more general in definition (ie.  alife is a type of
  complex system).  Usually complex system software takes the form of a

        itself revolves around breeding and training the alife
        creatures, 'Norns'. Its strikes a pretty nice balance between
        fun and science, or so I'm told.

        (summary written by Steve Grand included below)

        The eponymous creatures in this computer game are called Norns,
        and the world's population of them at one stage hovered around
        the five million mark, making them more common than many
        familiar natural species. Each norn is composed of thousands of
        tiny simulated biological components, such as neurons,
        biochemicals, chemoreceptors, chemoemitters and genes.  The
        norns' genes dictate how these components are assembled to make
        complete organisms, and the creatures' behaviour then emerges
        from the interactions of those parts, rather than being
        explicitly 'programmed in'.

        The norns are capable of learning about their environment,
        either by being shown things by their owners or through learning
        by their own mistakes. They must learn for themselves how to
        find food and how to interact with the many objects in their
        environment. They can interact with their owners, using simple
        language, and also with each other.  They can form relationships
        and produce offspring, which inherit their neural and
        biochemical structure from their parents and are capable of
        open-ended evolution over time. They can fall prey to a variety
        of diseases (as well as genetic defects) and can be treated with
        appropriate medicines.

     Langton's Ant

        Langton's Ant is an example of a finite-state cellular automata.
        The ant (or ants) start out on a grid. Each cell is either black
        or white.  If the ant is on a black square, it turns right 90
        and moves forward one unit. If the ant is on a white square, it
        turns left 90 and moves forward one unit.  And when the ant
        leaves a square, it inverts the color. The neat thing about
        Langton's Ant is that no matter what pattern field you start it
        out on, it eventually builds a "road," which is a series of 117
        steps that repeat indefinitely, each time leaving the ant
        displaced one pixel vertically and horizontally.

        PolyWorld is a computational ecology that I developed to explore
        issues in Artificial Life. Simulated organisms reproduce
        sexually, fight and kill and eat each other, eat the food that
        grows throughout the world, and either develop successful
        strategies for survival or die. An organism's entire behavioral
        suite (move, turn, attack, eat, mate, light) is controlled by
        its neural network "brain". Each brain's architecture--it's
        neural wiring diagram--is determined from its genetic code, in
        terms of number, size, and composition of neural clusters
        (excitatory and inhibitory neurons) and the types of connections
        between those clusters (connection density and topological
        mapping). Synaptic efficacy is modulated via Hebbian learning,
        so, in principle, the organisms have the ability to learn during
        the course of their lifetimes. The organisms perceive their
        world through a sense of vision, provided by a computer graphic
        rendering of the world from each organism's point of view. The
        organisms' physiologies are also encoded genetically, so both
        brain and body, and thus all components of behavior, evolve over
        multiple generations. A variety of "species", with varying
        individual and group survival strategies have emerged in various
        simulations, displaying such complex ethological behaviors as
        swarming/flocking, foraging, and attack avoidance.

        An aglet is a Java object that can move from one host on the
        Internet to another.  That is, an aglet that executes on one
        host can suddenly halt execution, dispatch to a remote host, and
        resume execution there. When the aglet moves, it takes along its
        program code as well as its state (data). A built-in security
        mechanism makes it safe for a computer to host untrusted aglets.
        The Java Aglet API (J-AAPI) is a proposed public standard for
        interfacing aglets and their environment. J-AAPI contains
        methods for initializing an aglet, message handling, and
        dispatching, retracting, deactivating/activating, cloning, and
        disposing of the aglet. J-AAPI is simple, flexible, and stable.

        conceptualization of goals and goal achievement is more
        classically defined (UMPRS is more behavioral performance-based
        than truly goal-based) and makes the distinction between plans
        to achieve goals and plans that simply encode behaviors. Goal-
        types implemented include achievement (attain a specified world
        state), maintenance (re-attain a specified world state), and
        performance. Execution of multiple simultaneous goals are
        supported, with suspension and resumption capabilities for each
        goal (i.e., intention) thread. JAM plans have explicit
        precondition and runtime attributes that restrict their
        applicability, a postcondition attribute, and a plan attributes
        section for specifying plan/domain-specific plan features.

        spyse is a development framework and platform for building
        multi-agent systems using the Python programming language. A
        multi-agent system (MAS) combines concepts from distributed
        computing and artificial intelligence.  Agents are autonomously
        reasoning software entities that can collaborate (or compete) in
        order to achieve a (common) goal. By cooperating they create
        emergent behaviour in the system (distributed artificial
        intelligence). The architecture of a MAS is specified in the
        FIPA standard.

        Spyse provides multiple means for reasoning (BDI logics, CLIPS
        expert shell, etc.) and communicating locally and remotely.

        Each agent has its own thread of control. Agents within and
        among instances of the platform communicate by exchanging
        messages based on ontologies. Spyse makes use of the Web
        Ontology Language (OWL) defined for the Semantic Web.

        An agent is a process that may migrate through a computer
        network in order to satisfy requests made by clients. Agents are
        an attractive way to describe network-wide computations.

        The TACOMA project focuses on operating system support for
        agents and how agents can be used to solve problems
        traditionally addressed by operating systems. We have
        implemented a series of prototype systems to support agents.

        TACOMA Version 1.2 is based on UNIX and TCP. The system supports
        agents written in C, Tcl/Tk, Perl, Python, and Scheme (Elk). It
        is implemented in C. This TACOMA version has been in public
        domain since April 1996.

        We are currently focusing on heterogeneity, fault-tolerance,
        security and management issues. Also, several TACOMA
        applications are under construction. We implemented StormCast
        4.0, a wide-area network weather monitoring system accessible
        over the internet, using TACOMA and Java. We are now in the

        FRP system with robotics library and graphical interactive
        robotics simulator.

        Functional reactive programming, or FRP, is a paradigm for
        programming hybrid systems  i.e., systems containing a
        combination of both continuous and discrete components  in a
        high-level, declarative way.  The key ideas in FRP are its
        notions of continuous, time-varying values, and time-ordered
        sequences of discrete events. Yampa is an instantiation of FRP
        as a domain-specific language embedded in Haskell.

        Curry is a universal programming language aiming to amalgamate
        the most important declarative programming paradigms, namely
        functional programming and logic programming. Moreover, it also
        covers the most important operational principles developed in
        the area of integrated functional logic languages: "residuation"
        and "narrowing" (there is an older survey and a newer survey on
        functional logic programming).

        Curry combines in a seamless way features from functional
        programming (nested expressions, higher-order functions, lazy
        evaluation), logic programming (logical variables, partial data
        structures, built-in search), and concurrent programming
        (concurrent evaluation of expressions with synchronization on
        logical variables). Moreover, Curry provides additional features
        in comparison to the pure languages (compared to functional
        programming: search, computing with partial information;
        compared to logic programming: more efficient evaluation due to
        the deterministic and demand-driven evaluation of functions).

        ECoLisp (Embeddable Common Lisp) is an implementation of Common
        Lisp designed for being embeddable into C based applications.
        ECL uses standard C calling conventions for Lisp compiled
        functions, which allows C programs to easily call Lisp functions
        and viceversa. No foreign function interface is required: data
        can be exchanged between C and Lisp with no need for conversion.
        ECL is based on a Common Runtime Support (CRS) which provides
        basic facilities for memory managment, dynamic loading and
        dumping of binary images, support for multiple threads of
        execution. The CRS is built into a library that can be linked
        with the code of the application. ECL is modular: main modules
        are the program development tools (top level, debugger, trace,
        stepper), the compiler, and CLOS. A native implementation of
        CLOS is available in ECL: one can configure ECL with or without
        CLOS. A runtime version of ECL can be built with just the
        modules which are required by the application. The ECL compiler
        compiles from Lisp to C, and then invokes the GCC compiler to
        produce binaries.

        and then uses the native optimizing C compilers (e.g., GCC).  A
        function with a fixed number of args and one value turns into a
        C function of the same number of args, returning one value, so
        GCL is maximally efficient on such calls.  It has a conservative
        garbage collector which allows great freedom for the C compiler
        to put Lisp values in arbitrary registers.

        It has a source level Lisp debugger for interpreted code, with

        GNU Prolog is a free Prolog compiler with constraint solving
        over finite domains developed by Daniel Diaz.

        GNU Prolog accepts Prolog+constraint programs and produces
        native binaries (like gcc does from a C source). The obtained
        executable is then stand-alone. The size of this executable can
        be quite small since GNU Prolog can avoid to link the code of
        most unused built-in predicates. The performances of GNU Prolog
        are very encouraging (comparable to commercial systems).

        Beside the native-code compilation, GNU Prolog offers a
        classical interactive interpreter (top-level) with a debugger.

        The Prolog part conforms to the ISO standard for Prolog with
        many extensions very useful in practice (global variables, OS
        interface, sockets,...).

        GNU Prolog also includes an efficient constraint solver over

        RScheme compiles to bytecodes which are interpreted by a

        YAP is a high-performance Prolog compiler developed at

        WAM (Warren Abstract Machine), with several optimizations for
        better performance. YAP follows the Edinburgh tradition, and is
        largely compatible with DEC-10 Prolog, Quintus Prolog, and
        especially with C-Prolog. Work on the more recent version of YAP
        strives at several goals:

        В·  Portability: The whole system is now written in C. YAP
           compiles in popular 32 bit machines, such as Suns and Linux
           PCs, and in a 64 bit machines, the Alphas running OSF Unix
           and Linux.

        В·  Performance: We have optimised the emulator to obtain
           performance comparable to or better than well-known Prolog
           systems. In fact, the current version of YAP performs better
           than the original one, written in assembly language.

        В·  Robustness: We have tested the system with a large array of
           Prolog applications.

        В·  Extensibility: YAP was designed internally from the beginning
           to encapsulate manipulation of terms. These principles were
           used, for example, to implement a simple and powerful C-
           interface. The new version of YAP extends these principles to
           accomodate extensions to the unification algorithm, that we
           believe will be useful to implement extensions such as
           constraint programming.

        В·  Completeness: YAP has for a long time provided most builtins
           expected from a Edinburgh Prolog implementation.  These
           include I/O functionality, data-base operations, and modules.
           Work on YAP aims now at being compatible with the Prolog

        В·  Openess: We would like to make new development of YAP open to
           the user community.

        В·  Research: YAP has been a vehicle for research within and
           outside our group. Currently research is going on on
           parallelisation and tabulation, and we have started work to
           support constraint handling.

        In EcoSim an ecosystem is described by all static and dynamic
        properties of the individuals involved in the system as well as
        time varying properties of the environment. Individuals change
        their state over time or due to internal and external events.
        The environment is also defined via dynamic objects which can
        change. Supports on the fly analysis and animation of generated
        data. It is a C++ class library designed to support individual-
        oriented modelling and simulation of ecological systems.

        IDEAL is a test bed for work in influence diagrams and Bayesian
        networks. It contains various inference algorithms for belief
        networks and evaluation algorithms for influence diagrams. It
        contains facilities for creating and editing influence diagrams
        and belief networks.

        IDEAL is written in pure Common Lisp and so it will run in
        Common Lisp on any platform. The emphasis in writing IDEAL has
        been on code clarity and providing high level programming
        abstractions. It thus is very suitable for experimental
        implementations which need or extend belief network technology.

        At the highest level, IDEAL can be used as a subroutine library
        which provides belief network inference and influence diagram
        evaluation as a package. The code is documented in a detailed
        manual and so it is also possible to work at a lower level on
        extensions of belief network methods.

        IDEAL comes with an optional graphic interface written in CLIM.
        If your Common Lisp also has CLIM, you can run the graphic

        Illuminator is a toolset for developing OCR and Image
        Understanding applications.  Illuminator has two major parts: a
        library for representing, storing and retrieving OCR
        information, heretofore called dafslib, and an X-Windows "DAFS"
        file viewer, called illum. Illuminator and DAFS lib were
        designed to supplant existing OCR formats and become a standard
        in the industry. They particularly are extensible to handle more
        than just English.

        QUANT/1 stands for type QUANTifier. It aims to be an alternative
        to Prolog-like (Resulutional-like) systems. Main features
        include a lack of necessity for eliminating Quantifiers,
        scolemisation, ease of comprehension, large scale formulae
        operation, acceptance of nonHorn formulaes, and Iterative
        deeping. The actual library implemented in this project is
        called ATPPCF (Automatic Theorem Prover in calculus of
        Positively Constructed Formulae).

        ATPPCF will be a library (inference engine) and an extension of
        the Predicate Calculus Language as a new logical language. The
        library will be incorporable in another software such as TCL,
        Python, Perl. The engine's primary inference method will be the
        "search of inference in language of Positively Constructed
        Formulas (PCFs)" (a subset of Predicate Calculus well translated
        in both directions). The language will be used as scripting
        language to the engine. But there will be possibility to replace
        it with extensions languages of main software.

        This program simulates primitive life-forms, equipped with some
        basic instincts and abilities, in a 2D environment consisting of
        cells.  By mutation new generations can prove their success, and
        thus passing on "good family values".

        The brain of a TIN can be seen as a collection of processes,
        each representing drives or impulses to behave a certain way,
        depending on the state/perception of the environment ( e.g.
        presence of food, walls, neighbors, scent traces) These behavior
        process currently are : eating, moving, mating, relaxing,
        tracing others, gathering food and killing. The process with the
        highest impulse value takes control, or in other words: the tin
        will act according to its most urgent need.
