This paper presents nonmonotonic quasi-Newton algorithms via two pre-conditional curvilinear paths, the preconditional modified gradient path and the precon-dit
In this paper,we give the sensitivity analyses by two approaches for L,D,U in factorization A= LDU of general perturbations in A which su fficiently small in no
The paper is concerned with solving periodic boundary problem of semilinear systems,which will be differentiably embedded into an one-parameter family of operat
