摘　　要：为克服标准粒子群算法存在的早熟现象,借鉴人类社会的联姻策略,提出了一种改进的粒子群优化算法。该算法通过部落联姻,避免了粒子基因过于接近;采用交叉策略,在一定程度上避免了过度破坏个体适应度的现象。在优化Rastrigin函数时,改进的算法显现出了优越性。最后,以电磁继电器优化设计为例,验证了基于联姻策略的粒子群优化算法的可靠性和有效性。A new particle swarm optimization（PSO） with allied strategy formed in the evolutionary process of human society had been introduced to avoid the premature problem in standard PSO.The improved PSO algorithm decreased the gene similarity by the allied strategy and protected the individual fitness through the crossover strate-gy.The superiority of new PSO had been verified when it was applied to optimize the Rastrigin function.The modi-fied PSO algorithm had been used for the optimal design of electromagnetic relay and the results had verified its val-idation and reliability.
