A new spectral conjugate gradient method for solving unconstrained optimization problems

Abstract EN

The spectral conjugate gradient methods are fascinating, and it has been shown that they are useful for strictly convex quadratic reduction when used properly.

to handle large scale unconstrained optimization issues, a novel spectral conjugate gradient approach is suggested in this study.

we devise a new methodology for determining the spectral and conjugate parameters, motivated by the benefits of the approximate optimum step size strategy utilized in the gradient method.

additionally, the new search direction meets the spectral property as well as the sufficient descent criterion.

the presented method's global convergence is established under a set of appropriate assumptions.
