摘要
介绍了一种优化方法——围法,该方法的基本原理是利用函数等值线封闭且互不相交。主要介绍初始点的选择、其余点的生成、迭代终止的判断以及此方法的优缺点,并以实例形式详细演示了该方法的应用,结果表明了该方法的准确性和可靠性。
In this paper,a new optimization method named surround method is introduced. and Its bases upon isoclines of function are closed and doesn′t intersect with each other. It mainly introduces the selection of initial point,production of other points,estimation of the iterative end,and its advantages and disadvantages of the method. A demonstration,which is done in details at the end of the paper,show that this method has good veracity and stability.
