Abstract

This paper presents a new method for global optimization. We use exact quadratic regularization for the transformation of the multimodal problems to a problem of a maximum norm vector on a convex set. Quadratic regularization often allows you to convert a multimodal problem into a unimodal problem. For this, we use the shift of the feasible region along the bisector of the positive orthant. We use only local search (primal-dual interior point method) and a dichotomy method for search of a global extremum in the multimodal problems. The comparative numerical experiments have shown that this method is very efficient and promising.

一种新的全局优化方法
本文提出了一种新的全局优化方法。利用精确二次正则化将多模态问题转化为凸集上的最大范数向量问题。二次正则化通常允许您将多模态问题转换为单模态问题。为此,我们利用可行域沿正正交线平分线的位移。我们只用局部搜索(原始对偶内点法)和二分法来搜索多模态问题的全局极值。数值对比实验表明,该方法是非常有效的,具有广阔的应用前景。
