Abstract: In this paper, we propose a modified Fletcher–Reeves conjugate gradient method. The new search direction is calculated in such a way that it is close to a three term PRP conjugate gradient method. In particular,… read more here.

Abstract: In this paper, we propose a spectral Fletcher–Reeves conjugate gradient-like method for solving unconstrained bi-criteria minimization problems without using any technique of scalarization. We suggest an explicit formulae for computing a descent direction common to… read more here.

DOI: 10.1371/journal.pone.0320416
Abstract: The spectral conjugate gradient (SCG) technique is highly efficient in addressing large-scale unconstrained optimization challenges. This paper presents a structured SCG approach that combines the Quasi-Newton direction and an extended conjugacy condition. Drawing inspiration from… read more here.
