Automatic Evolution of Java-Written Game Heuristics

摘要

Finch is a methodology for evolving Java bytecode, enabling the evolution of extant, unrestricted Java programs, or programs in other languages that compile to Java bytecode. The established approach in genetic programming (GP) involves the definition of functions and terminals appropriate to the problem at hand, after which evolution of expressions using these definitions takes place. FINCH evolutionarily improves actual, extant software, which was not intentionally written for the purpose of serving as a GP representation in particular, nor for evolution in general. In this work we show how several game heuristics that are taken as real-world Java programs are effortlessly and automatically improved by FINCH.
