An Inexact Optimal Hybrid Conjugate Gradient Method for Solving Symmetric Nonlinear Equations
This article presents an inexact optimal hybrid conjugate gradient (CG) method for solving symmetric nonlinear systems. The method is a convex combination of the optimal Daiā€“Liao (DL) and the extended three-term Polakā€“RibiĆ©reā€“Polyak (PRP) CG methods. However, two different formulas for selecting the convex parameter are derived by using the conjugacy ā€¦
