A New Conjugate Gradient Type Formula

Hong Ling

Abstract

In this paper,we present a new conjugate gradient method for unconstrained optimization and proved that with the strong Wolfe line search the new method can support the global convergence result.At the same time,the new conjugate gradient algorithm satisfies the sufficient descent property.We also obtained better numerical results by this algorithm.
