A Spectral Dai-Yuan-Type Conjugate Gradient Method for Unconstrained Optimization
A new spectral conjugate gradient method (SDYCG) is presented for solving unconstrained optimization problems in this paper. Our method provides a new expression of spectral parameter. This formula ensures that the sufficient descent condition holds. The search direction in the SDYCG can be viewed a...
