## The Lagrangian Relaxation for the Combinatorial Integral Approximation Problem

We are interested in methods to solve mixed-integer nonlinear optimal control problems (MIOCPs) constrained by ordinary dierential equations and combinatorial constraints on some of the control functions. To solve these problems we use a rst discretize, then opti- mize approach to get a specially structured mixed-integer nonlinear program (MINLP). We decompose this MINLP into an … Read more
