LibGA:

LibGA is a library of routines written in C for developing GENETIC ALGORITHMs. It is fairly simple to use, with many knobs to turn. Most GA parameters can be set or changed via a configuration file, with no need to recompile. (E.g., operators, pool size and even the data type used in the CHROMOSOME can be changed in the configuration file.) Function pointers are used for the GENETIC OPERATORs, so they can easily be manipulated on the fly. Several genetic operators are supplied and it is easy to add more. LibGA runs on many systems/architectures. These include Unix, DOS, NeXT, and Amiga.

LibGA Version 1.00 is available by FTP from ftp://ftp.aic.nrl.navy.mil/pub/galist/src/ga/libga100.tar.Z or by email request to its author, Art Corcoran <corcoran@penguin.mcs.utulsa.edu> (Unverified 8/94).
