Cut-and-branch and branch-and-cut

Description

Solving a MIP by cut-and-branch or branch-and-cut: using the default functionality 'addcuts' for local cuts (clean.mos/cleanm.mos), or alternatively using 'storecuts' and 'loadcuts' to obtain global cuts (cleansl.mos/cleanslcm.mos)

Further explanation of this example: Xpress Whitepaper 'Embedding Optimization Algorithms', Section 'Office cleaning: callbacks for branch-and-cut', and 'Mosel User Guide', Section 11.1 Cut generation
