The particle swarm optimization (PSO) algorithm is a stochastic optimization algorithm that does not converge to a global optimal solution on the basis of probability 1. In this paper, we present a new probability-based convergent PSO algorithm that introduces two mutation operators with exploration and exploitation abilities, which are applied to the previous best position of a particle with a certain probability. This algorithm converges to the-optimum solution on the basis of probability 1.We applied the proposed algorithm in 13 typical test functions and compared its performance with that of other PSO algorithms. Our numerical results show that the proposed algorithm can improve solution precision and convergence speed.
