CONVERGENCE AND OPTIMALITY CONDITIONS OF GLOBAL EXTREME WITH ADAPTIVE CHANGE OF DOMAIN
【摘要】 <正> [1]中讨论了变量区域适时变动时总极值问题,构造了如下算法模型: 给定有界闭区域序列{Gk}和c0,设f(x)为Rn中有下界的连续函数。 令H0={x|f(x)≤c0,x∈G0},若μ(H0)=0,则c0即为G0上总极小值,H0为总极小点集(证明参见[2]),算法终止,故不妨设μ(H0)>0, 作
【Abstract】 In reference[1] the problem of global extreme with adaptive change of domain was discussed, and the algorithm model was also constructed.In reference[2], the opiimalily conditions of global extreme with fixed domain was discussed.In this paper, we discuss the convergence and cptimality conditions of global extreme with adaptive change of domain. Theorem 2 and theorem 5 are chief results. Theorem 2 give the sufficient and neccessaiy condition of the convrgence of the algorithm in [1]; theorem 5 give the global optimality sufficient and neccessary condition for x , which is obtained by algorithm in [1]. These results are generalizations of the results in [1],[2].
