LaGO (Lagrangian Global Optimizer) is a MINLP solver developed in the DFG-project ”Optimization of a Complex Energy Conversion Plant”. Using the default parameter settings, LaGO is an implementation of a Branch-and-Cut solver for block-separable not necessarily convex MINLPs. This algorithm is illustrated in the recent paper ”LaGO - a (heuristic) Branch and Cut algorithm for nonconvex MINLPs” and in the slides of the talk ”LaGO - Branch and Cut for nonconvex block-separable MINLPs in the absence of algebraic formulations”.
