Abstract: In this paper, we proposed a spectralgradient-Newton two phase method for constrained semismooth equations. In thefirst stage, we use the spectral projected gradient to obtain the globalconvergence of the algorithm, and then use the final point in the first stageas a new initial point to turn to a projected semismooth asymptotically newtonmethod for fast convergence.
