- Abstract
We propose a variant of the conjugate gradient method for solving large-scale systems of symmetric nonlinear equations, in which the spectral secant condition and conjugate gradient ideas are combined. Using an approximate norm descent, we show that the proposed method has global convergence properties. Under appropriate conditions, numerical results for benchmark test functions, demonstrate an improved efficiency of this method over other existing alternatives.
