Parallel Genetic Algorithms (PGAs) were used to simultaneously optimize the structure and weights for feed-forward neural networks. Aiming at its large-scale application in common distributed network system, a concentrative coarse-grained model for parallel evolutionary neural networks is designed and realized in a laboratorial distributed computation environment. The initial results of experiments indicate that the parallel model can quicken the searching process and improve the evolutionary efficiency.
