The library definesa class hierarchy.  An integral component is the ability to produceautomatically defined functions as found in Koza's "GeneticProgramming II".Technical documentation in postscript format can be found in the "doc"directory.  There is also a short introduction into geneticprogramming (by Adam Fraser).This system includes everything you ever wanted from a geneticprogramming system but were always afraid to ask for, such as....- Automatically defined functions (ADFs).- Tournament and fitness proportionate selection.- Demetic grouping- Optional steady state genetic programming kernel (like the AdamFraser code).  Steady state means that not a complete new populationis built up every generation, but bad performing GPs are replaced bynewly evolved ones.  This uses approximately half the memory!- Subtree crossover.- Swap and shrink mutation.- A way of changing every parameter of the system withoutrecompilation.- Capacity for multiple populations (if you have the resources).- Loading and saving of populations and genetic programs.- Standard random number generator for complete portability.  This hasbeen improved: population sizes of over 250000 are possible now.- Explanations of how to write the modules for evolving code.- Examples.- And the best thing for the experts: A parameter study about theinfluence of every important parameter.- Completely ANSI C++ compliant.- Full and wonderful comments dispersed throughout the code.- Internal parameter checks (can be turned off by a compiler switch).Even if the programmer makes a mistake, the kernel complains.This C++-code makes not use of templates and exceptions, so no C++compatibility problems should arise.
