A scaled three-term conjugate gradient method for unconstrained optimization by Arzuka, Ibrahim, Abu Bakar, Mohd Rizam, Leong, Wah June

“…In this paper, we propose an efficient three-term conjugate gradient method by utilizing the DFP update for the inverse Hessian approximation which satisfies both the sufficient descent and the conjugacy conditions. The basic philosophy is that the DFP update is restarted with a multiple of the identity matrix in every iteration. …”
