Preconditioned Three-Term Conjugate Gradient Framework for Nonconvex Finite Minimax Problems

This paper develops a hyperbolic-majorization preconditioned three-term nonlinear conjugate-gradient framework for nonconvex finite minimax optimization. An analytic symmetric positive definite metric is derived from a global quadratic majorization of the hyperbolic smoothing model and is used simultaneously as a curva...
