Abstract EN
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 as a combination of the spectral gradient and the Dai-Yuan conjugate gradient.
The global convergence of the SDYCG is also obtained.
Numerical results show that the SDYCG may be capable of solving large-scale nonlinear unconstrained optimization problems.
