Hybrid particle swarm optimization algorithm

    Abstract: Since many scientific and engineering practice problems from either the pursuit of better-parameter optimization optimization results, so a large number of domestic and foreign scholars have studied the optimization algorithm.Wherein the particle swarm optimization (PSO) is a widely recognized good algorithm. Hybrid particle swarm algorithm is based on the PSO, drawing on a number of other intelligent optimization algorithm thought and the formation of particle swarm optimization.For example: genetic algorithms, simulated annealing algorithm and neural network intelligent algorithms that are currently used widely in intelligent algorithms, intelligent algorithms as each has its own characteristics, so naturally there is formed combining the advantages of a variety of intelligent algorithms hybrid intelligent algorithm.

    This article describes three hybrid particle swarm algorithm, the first genetic algorithm mechanism of natural selection improved particle swarm algorithm based on the second mechanism is based on the hybridization improved particle swarm algorithm, and the third is based on simulated annealing algorithm particle swarm optimization. Through simulation and comparative study of the three hybrid particle swarm algorithm accuracy and stability and other aspects of comparative advantages and disadvantages.
