Particle swarm optimization (PSO) algorithm is frequently employed to solve various optimization problems, but it easily gets into the local extremum in later evolution period. An improved chaos search strategy is introduced into PSO algorithm. When particles get into the local extremum, they are activated by chaos search strategy, and chaos search area are(More)
A geometric constraint solving method based on improved chaos-particle swarm optimization (PSO) algorithm is proposed, which transforms traditional geometric constraint solving problem into optimization problem. Because PSO easily gets into local extremum in later evolution period and leads to low precision, an improved chaos search strategy is used to(More)
