Cut generation for an economic lot-sizing (ELS) problem Description This model implements various forms of cut-and-branch and branch-and-cut algorithms. In its simplest form (looping over LP solving) it illustrates the following
features:
Another implementation (main model: runels.mos, submodel: elsp.mos) parallelizes the execution of several model instances, showing the following features:
Further explanation of this example: elscb.mos, elsglobal.mos, runels.mos: Xpress Whitepaper 'Multiple models and parallel solving with Mosel', Section 'Solving several model instances in parallel'.
