§ 1 IntroductionIn this paper we consider the following unconstrained optimization problem:minx∈ Rnf( x) , ( 1 )where f:Rn→R is a convex LC1 function,i.e.,a continuously differentiable convex func-tion whose gradient is Lipschitz continuous.We call the problem( 1 ) a convex LC1 opti-mization problem.This problem is an importantsubjectin nonlinear optimization.Applica-tions of such a minimization problem include stochastic quadratic programs[1 ,2 ] and the ex-tended linear-quadratic pro… 相似文献

约束极值的一个可行方向法 总被引:1,自引:0,他引:1
<正> 引言我们讨论下面的约束极值问题(NP):(?)f(x_1,x_2,…,x_n) (1)(NP)R={x|a_j~Tx≤b_j,x∈E~n,j∈I},I={1,2,…,m}.(2)其中 a_j=(a~(j_1),a_(j_2),…a_(j_n))~T,x~T=(x_1,x_2,…,x_n)是 n 维向量,b_j 是标量,f(x_1,x_2,…,x_n)是一阶连续可微的凸函数. 相似文献
