Abstract
并行算法是当前研究解决算法效率问题的成熟技术之一。为提高GEP算法解决复杂函数优化问题的效率,将并行算法引入多细胞基因表达式编程函数优化问题,解决传统计算形式不能充分发挥多核处理器性能的问题。通过分析多细胞基因表达式编程并行算法的机理和M PI和O pen M P混合并行模型,设计与实现多细胞基因表达式编程函数优化的并行算法(Parallel Multicellular Gene Expression Programming algorithm for Function Optimization) PGMFO。实验结果表明针对复杂的函数优化问题,在不影响精度和收敛性的情况下,PGMFO算法比原有的算法效率高出10%~20%。
