Global Selection Methods for Massively Parallel Computers

In this paper, the parallel implementation of various selection operators in evolutionary algorithms on massively parallel 2-dimensional arrays is treated. Novel parallel versions of fitness proportionate, linear ranking, and tournament selection are presented and compared. It is found that these algorithms can be implemented such that their expected behaviour is identical or very close to those of the sequential algorithms from which they originated, but with the advantage of significant speed improvements associated with parallelism.
