A fast approximate column-and-constraint generation method for two-stage robust mixed-integer programs
Marc Goerigk, Dorothee Henke, Johannes Kager +2
This paper presents a new column-and-constraint generation method for two-stage robust mixed-integer programs with finite uncertainty sets. Our method combines and extends speed-up…
