Many optimization problems in science and technology are subject to a system of nonlinear constraints combined with discrete decisions. Mathematically, these problems can be modeled as mixed-integer nonlinear programs (MINLPs), since they can represent both nonlinear correlations and discrete decisions. However, the interaction of integrality and nonlinearity poses a major challenge in solving these problems. In this thesis, we propose a method for solving MINLPs to global optimality by discretization of the occurring nonlinearities. Our approach requires only continuous nonlinearities with bounded domains and is thus suitable for a wide range of MINLP problems. The emphasis is on using sophisticated and reliable mixed-integer linear pro...
