Description
Summary:In this paper, we propose a new exact penalty function method for solving a class of semi-infinite programming problems (SIPs). We introduce a logarithmic form function of the constraint violation, where the constraint violation is a measure of the violation of the constraints of the current iterate. By appending it to the objective function, we obtain a sequence of approximate conventional unconstrained optimization problem. It is proved that when the penalty parameter is sufficiently large, any local minimizer of the approximate problem is a local minimizer of the original problem. Numerical results show that the proposed method is effective.
