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., \(\bf 267\) (2016), 297--300] based on the...
