Improving the Performance of MIP and MINLP Solvers by Integrated Heuristics

This article provides an overview of the author’s dissertation (Berthold, Heuristic algorithms in global MINLP solvers, 2014, [4]). We study heuristic algorithms that are tightly integrated within global MINLP solvers and analyze their impact on the overall solution process. This comprises generalizations of primal heuristics for MIP towards MINLP as well as novel ideas for MINLP primal heuristics and for heuristic algorithms to take branching decisions and to collect global information in MIP.
