The convergence properties of some descent conjugate gradient algorithms for optimization models

The three-term conjugate gradient (CG) algorithms are among the efficient variants of CG method for convex and nonconvex functions.This is because most three-term algorithms are constructed using the classical CG method whose numerical performance has been tested and convergence proved.In this paper, we present a modification of RMIL+ CG method proposed by Dai [Z.Dai, Appl.Math.Comput., 267 (2016), 297-300] based on the convergence analysis of...
