摘    要:为有效解决标准粒子群(PSO)算法在进化后期缺乏多样性且精度不高的问题,利用多核系统及实际高校地理数据,给出一种高校数据的整数规划方法及并行自平衡PSO算法模型来并行求解高校路网问题,同时体现算法性能。将自平衡机制采用多核系统并行处理方式生成相互独立的子群体,每个子群体间并行求解,最终生成主群体最优路径即高校路网。在Visual Studio2005.NET环境下用C++编程实现仿真。实验结果表明,此算法从求解精度及计算时间两个重要方面综合改善了算法性能。

关 键 词:并行处理  并行自平衡PSO算法  高校路网

Abstract:To effectively solve the problem of the standard particle swarm (PSO) algorithm, which is the lack of diversity and not high accuracy, this paper uses multi-core systems and actual universities geographic coordinates. Then it gives an integer pro- gramming and parallel self-balancing PSO algorithm to solving university path. Self-balancing mechanism uses parallel processing of multi-core systems to generate independent sub-groups. Every sub-group can do parallel computation and finally generate the optimal path of the main group. It uses C ++ programming in Visual Studio 2005 . NET to realize simulation. The results show that this algorithm improves the performance of the PSO algorithm from the solution accuracy and computation time which are two important aspects.
Keywords:parallel processing  parallel self-balancing PSO algorithm  university path
