Particle Swarm Optimization algorithm (PSO) is a population-based stochastic optimization techniques.In this paper

the EDA algorithm and PSO algorithm combine to form a new improved algorithm (EPSO) .The EPSO algorithms can effectively global statistics and global optimal solution used in the solution space search

the EPSO algorithm for solving the multidimensional knapsack problem.Experimental results show that solving the multidimensional knapsack problem

the EPSO is better than the traditional PSO algorithm

as well as a variety of heuristic intelligent algorithms

and at the same time

the EPSO Algorithm using fewer parameters

and therefore easy to implement

run more stable.
