Accelerated derivative-free spectral residual method for nonlinear systems of equations
Ernesto G. Birgin, John L. Gardenghi, Diaulas S. Marcondes +1
Spectral residual methods are powerful tools for solving nonlinear systems of equations without derivatives. In a recent paper, it was shown that an acceleration technique based on…
