A multivariate spectral hybridization of HS and PRP method for nonlinear systems of equations
Hassan Mohammad
We present a multivariate spectral hybridization of Hestenes-Stiefel (HS) and Polak-Ribiere-Polyak (PRP) method for solving large-scale nonlinear systems of equations. The search d…
Iterative algorithm with structured diagonal Hessian approximation for solving nonlinear least squares problems
Aliyu Muhammed Awwal, Poom Kumam, Hassan Mohammad
Nonlinear least-squares problems are a special class of unconstrained optimization problems in which their gradient and Hessian have special structures. In this paper, we exploit t…
A diagonal PRP-type projection method for convex constrained nonlinear monotone equations
Hassan Mohammad
Iterative methods for nonlinear monotone equations do not require the differentiability assumption on the residual function. This special property of the methods makes them suitabl…
Structured two-point stepsize gradient methods for nonlinear least squares
Hassan Mohammad, Mohammed Yusuf Waziri
In this paper, we present two choices of structured spectral gradient methods for solving nonlinear least-squares problems. In the proposed methods, the scalar multiple of identity…
