Computer-based problem solving systems that use computational models of evolutionary processes as the key elements in design and implementation. A number of evolutionary computational models have been proposed, including evolutionary algorithms, {genetic algorithm}s, the {evolution strategy}, {evolutionary programming}, and {artificial life}. {The Hitchhiker' s Guide to Evolutionary Computation (http://www.cis.ohio-state.edu/hypertext/faq/bngusenet/comp/ai/genetic/top.html)}. {Bibliography (http://liinwww.ira.uka.de/bibliography/Ai/EC-ref.html)}.
