Genetic Algorithms and Evolutionary Computing
epgpu version 0.99
The first evolutionary computing program implemented on GPU. It performs accurate and extremely fast evolutionary computing. The goal of this implementation is to speedup, not just the evolutionary computation, but also the research of evolutionary computing by allowing the execution of evolutionary algorithms on low-cost graphics accelerators equipped on ordinary PCs. The source code is completely free for both commercial and academic uses.
