| Abstract: | An improved particle swarm optimization algorithm is given to solve nonlinear integer pro- gramming problems. In the algorithm, the velocity equation and the position equation of the particle swarm optimization model are improved, and a dynamic-objective constraint-handing method is used to improve the ability to select the optimal points and the acceleration optimization strategies of the parti- cle＇s neighborhood is joined to improve the local optimal ability. Experimental results show that the proposed algorithm has a high solution efficiency and stability. |
