A Effective Parameter for Dai Liao Family of Conjugate Gradient Methods Based on Modified Secant Equation

In this paper, we present a new value of the parameter t in Dai Liao Conjugate Gradient Method. Under mild assumptions, we establish the global convergence property of the proposed method. Numerical results on some test problems in the CUTEst library illustrate computational efficiency of the new method.
