A NONMOTOTONE ALGORITHM FOR MINIMIZING NONSMOOTH COMPOSITE FUNCTIONS
《Numerical Mathematics A Journal of Chinese Universities(English Series)》1997年第2期152-162,共11页孙小玲 张连生 
In this paper, we present a nonmonotone algorithm for solving nonsmooth composite optimization problems. The objective function of these problems is composited by a nonsmooth convex function and a differentiable funct...

A SQP METHOD FOR MINIMIZING A CLASS OF NONSMOOTH FUNCTIONS
《Numerical Mathematics A Journal of Chinese Universities(English Series)》1996年第2期139-146,共8页孙小玲 张连生 白延琴 
In this paper,we present a successive quadratic programming(SQP)method for minimizing a class of nonsmooth functions,which are the sum of a convex function and a nonsmooth composite function.The method generates new i...

NONDESCENT SUBGRADIENT METHOD FOR NONSMOOTH CONSTRAINED MINIMIZATION
《Numerical Mathematics A Journal of Chinese Universities(English Series)》1994年第2期126-134,共9页徐慧福 
A kind of nondecreasing subgradient algorithm with appropriate stopping rule has been proposed for nonsmooth constrained minimization problem. The dual theory is invoked in dealing with the stopping rule and general g...
