Abstract

Genetic algorithms (GAs) are becoming increasingly popular for signal detection, often in conjunction with neural networks. The time-intensive nature of these techniques has fostered an interest in parallel implementations. Genitor is a widely used algorithm belonging to the class of steady-state GAs which are generally believed to contain little exploitable parallelism. Parallel versions have involved fundamental changes to the algorithm by introducing islands. This paper describes how Genitor can be parallelized virtually as is, with nearly linear speedup, by rearranging the order of some of the genetic operations. An analytical method is derived which can be used for determining the amount of parallelism that can be achieved. An implementation for a shared-memory machine is described, and the resulting execution is shown to support the analysis.
