Abstract: The semi-infinite programming problem arises from various applications. It is hard to solve because of its infinite constraints. On the other hand, the generalized Newton method, including the semismooth Newton method and the smoothing Newton method, is a powerful tool to solve some nonlinear optimization problems with complicated structures. The main advantages of the generalized Newton method are its superlinear and global convergence, and its easy subproblems as systems of linear equations. In this talk, we review the efforts to apply the generalized Newton method to the semi-infinite programming problem. The latest approach includes a constrained nonsmooth equations reformulation of the semi-infinite programming problem, a smoothing approximation to a nonsmooth aggregated form of the infinite constraints, and efforts on large-scale computation.
