“…is is the so-called smoothing Newton method. is class of methods has been successfully applied to solving lots of optimization and related problems, including linear complementarity problems [19][20][21][22][23][24], linear programs [25], nonlinear complementarity problems [26][27][28][29][30], variational inequalities [27,31], semidefinite complementarity problems [32][33][34][35][36][37], system of inequalities [19,34], symmetric cone complementarity problems [35,36], mathematical programs with complementarity constraints [38,39], and absolute value equations [40]. In order to achieve the global convergence, most of the known smoothing Newton methods require the assumption that the solution set of the concerned problem is nonempty and compact.…”
