Abstract
Mind Evolutionary Algorithm (MEA) imitates the human mind evolution by using similartaxis and dissimilation operations,which overcomes the prematurity and improves searching efficiency. But the addition of naturally washed out temporary subpopulations is blind and random; the existing searching modes are easily to fall into local convergence.This paper proposed Differential Mind Evolutionary Algorithm (DMEA), which saved the excellent genes in the evolution and brought adequate diversity to the population by introducing the thought of difference into dissimilation operation.Then DMEA is used in the synthesis of circular sparse antenna arrays.The excellent results of computer simulation show the advantage of array antenna patterns synthesis using DMEA.
心智进化算法(MEA)通过相似和异化运算来模拟人类的心智进化，克服了心智进化的早熟性，提高了搜索效率。但是，自然淘汰的临时亚种群的增加是盲目和随机的;现有的搜索模式容易陷入局部收敛。差分思维进化算法(Differential Mind evolution Algorithm, DMEA)通过在异化操作中引入差分思想，使进化过程中保留了优秀的基因，使种群具有足够的多样性。然后将DMEA应用于圆形稀疏天线阵的合成。计算机仿真的良好结果表明了采用DMEA合成阵列天线方向图的优越性。
