ARTIFICIAL INTELLIGENCE

SAMUEL, developed at the Naval Research Laboratory, is a heuristic learning
program that uses genetic algorithms and other competition-based
heuristics to improve its decision-making rules. The system actively
explores alternative behaviors in simulation, and modifies its rules based
on this experience. SAMUEL is designed for problems in which the payoff is
delayed in the sense that payoff occurs only at the end of an episode that
may span several decision steps. SAMUEL is particularly well-suited for
learning strategies in competitive environments. Research with SAMUEL has
focused on tasks such as predator-prey problems, tracking problems, and
other models of conflict.

SAMUEL is written in C-language for use on Sun series computers running
SunOS (inventory number DOD-00101) and IBM PC compatibles running MS-DOS
(inventory number DOD-00102). SAMUEL is available by license for an
unlimited time period. The licensed program product includes the SAMUEL
source code and one set of supporting documentation. Additional
documentation may be purchased separately at the price indicated below.
The program requires 2Mb of RAM for execution. Both a text-based and
graphical user interface version are provided with the Sun version. The
graphical user interface requires Solaris' OpenWindows Developer's Guide
2.0 or 3.0 (available from Sun Microsystems, 1800-873-7869) and Sun's
OpenWindows version 2.0 or 3.0. Sample Sun-4 executables are provided for
the text interface version. The DOS version has a command line interface.
The standard distribution medium for the Sun version of SAMUEL is a .25
inch streaming magnetic tape cartridge in UNIX tar format. The standard
distribution medium for the DOS version is a set of two 360K MS-DOS format
diskettes. The contents of the diskettes are compressed using the PKWARE
archiving tools. The utility to unarchive the files, PKUNZIP.EXE, is
included. The distribution media for both machine versions includes an
electronic copy of the documentation in PostScript format. License fee
$200.
