Abstract
Significant advances have been made in the last two decades for the effective solution of Mixed Integer Non-Linear Programming (MINLP) problems, mainly by exploiting the special structure of the problem that results under certain convexity assumptions. A number of decomposition based algorithms have been developed based on the concepts of projection, outer approximation and relaxation. For the case of non-convex MINLPs a number of deterministic global optimization algorithms have been introduced mainly based on branch and bound strategies. In this paper we present a novel decomposition algorithm to solve MINLP problems under the assumptions that the objective function is convex, the set of equality and inequality constraints are either convex, concave or quasi-concave functions and are continuous and once differentiable. The proposed approach is based on the idea of closely approximating the feasible region defined by the set of constraints by a convex polytope using the simplicial approximation approach. Convergence of the algorithm along with a number of computational examples are presented illustrating the applicability and efficiency of the proposed approach.
