PSO
Rosenbrock函数优化属于无约束函数优化问题,其全局极小值位于一条平滑而狭长的抛物线形状的山谷底部,且为优化算法提供的信息很少,因此找到其全局极小值就显得很困难。根据Rosenbrock函数的这种特性,专门提出了一种改进的PSO算法,该算法引入三角函数因子,利用三角函数具有的周期振荡性,使每个粒子获得较强的振荡性,扩大每个粒子的搜索空间,引导粒子向全局极小值附近靠近,避免算法过早地收敛,陷入局部最优,从而找到Rosenbrock函数的全局极小值。大量实验结果表明,该算法具有很好的优化性能,为某些领域某些特定的类似于Rosenbrock函数的优化问题提供了一种新的思路。(Rosenbrock function optimization functions are unconstrained optimization problems, its global minimum value at a smooth parabolic shape and narrow mountain valley
Department, and for the optimization algorithm provides little information, and therefore find its global minimum value becomes very difficult. According to this feature Rosenbrock function, specifically mentioning
Out an improved PSO algorithm (PSO-R), the algorithm introduced trigonometric factor, using trigonometric has periodic oscillations, so that each particle to obtain more
Strong oscillations of expanding the search space of each particle, the particle is close to nearby guide global minimum, avoiding premature convergence algorithm, into a local optimum, thus
Finding the global minimum Rosenbrock function. Experimental results show that the algorithm has a good optimizing performance, similar to some certain areas
Rosenbrock function in the optimization problem provides a new way of thinking.)
