Exposing origin-seeking bias in PSO

摘要

We discuss testing methods for exposing origin-seeking bias in PSO motion algorithms. The strategy of resizing the initialization space, proposed by Gehlhaar and Fogel and made popular in the PSO context by Angeline, is shown to be insufficiently general for revealing an algorithm's tendency to focus its efforts on regions at or near the origin. An alternative testing method is proposed that reveals problems with PSO motion algorithms that are not visible when merely resizing the initialization space.
