英文摘要：

A revised selection particle swarm optimization（RSPSO） algorithm was presented for solving constrained optimization problems.In this algorithm a method of dynamic multi-stage penalty function was used to process the constraint,a revised selection strategy was supplemented for constraint violation,and use a linear decreasing the tolerance degree of constraint violation to guide the individual particle,i.e.use modified feasibility-based rule to update the individual extremum and global extremum to guide the individual particle fly to the feasible region as soon as possible.Taking into consideration the influence of local information around each particle＇s impact on its future fly,the optimized velocity equation of basic particle swarm was modified.Numerical simulation showed that the algorithm presented exhibited a higher computation accuracy,better stability,stronger ability for global optimization.
