being trapped in local optimum

Experimental results show that the proposed algorithm not only has great advantages of convergence property over standard PSO, but also avoids effectively being trapped in local optimum.

实验结果表明，该算法具有较快的收敛速度和较高的收敛精度，能有效避免早熟收敛问题。

The basic principle of CPSO algorithm is that chaos initialization is adopted to improve individual quality and chaos perturbation is utilized to avoid the search being trapped in local optimum.

该算法的思想是采用混沌初始化进行改善个体质量和利用混沌扰动避免搜索过程陷入局部极值。
