摘　　要：针对粒子群优化算法(PSO)容易陷入局部最优值的缺点,提出一种基于遗传算法模式定理思想改进的粒子群优化算法(IPSO).新算法改善了粒子群优化算法摆脱局部极小点的能力.对典型函数的测试表明,IPSO算法的全局搜索能力有了显著提高,特别是对多峰函数能有效地避免早熟收敛问题.将改进的粒子群优化算法用于氧化反应动力学参数的优化,计算结果表明,新算法优化结果明显优于文献报道.An improved particle swarm optimization algorithm （IPSO） is proposed based on the idea of schema optimal choice, which is the basic character of genetic algorithm. The IPSO has merits of both PSO and genetic algorithm choice. Both IPSO and basic PSO are used to resolve several well-known benchmark functions optimation problems. Results show that IPSO has greater efficiency and better performance than PSO, especially to the highdimesional, multi-apices functions. The application of IPSO to estimate of the kinetic parameters of 2-chloropheol oxidation in supercritical water provides better parameters than those reported in the literature.
