摘要 为降低粒子群优化算法(PSO:Particle Swarm Optimization)时间和空间的复杂度随问题规模的增大而越来越高的问题,对图形处理器(GPU:Graphic Processing Unit)用于并行计算的方法进行了分析,利用GPU的并行特性,实现了粒子群优化算法路径搜索过程的并行化。测试函数实验结果证明,GPU平台较CPU模式下的计算,其搜索速率有明显提高。 In order to reduce the PSO(Particle Swarm Optimization) in time and space on the complexity of the problem,the GPU(Graphic Processing Unit)for parallel computing method is analized.Using GPU parallel characteristic,Particle PSO path search process in GPU platform is achied in paralled,Function test results show that the GPU mode is greater than the CPU mode calculation improve search speed.
