Abstract: We proposed a multiobjective particle swarm optimization algorithm based on selfadaption partition of searching space, according to the search capability and scale of particles, it was transformed into a multidimensional standard normal distribution with the volume of subsearch space, which finely partitioned search spaces and optimized the distribution of particles in the divided subsearch spaces, and the partition continued during iteration until an optimal solution set was obtained. The experimental results show that the algorithm effectively solves the problem that multiobjective particle swarm optimization algorithm is easy to fall into local extremum, compared with some typical multiobjective particle swarm optimization algorithms, the algorithm has significant advantages in diversity of population and convergence of solution on the performance index of inverted generational distance.
Key words: particle swarm optimization (PSO), multiobjective optimization problem (MOP), multidimensional standard normal distribution, selfadaption partition
