Global optimization, differential evolution, parallel migration model, migration topology, comparison on benchmark functions

The in?uence of parallelism on the performance of differential evolution is studied. Performance of non-parallel and two kinds of parallel topology is compared experimentally. The parallel versions were implemented on a single-processor machine and the in?uence of parallelism is simulated in the pseudo-parallel regime. The results show that parallel version of differential evolution with star topology exhibits the best efficiency among algorithms in comparison on the benchmark problems.
