Overview

The MIP solution enumerator (XPRSmipsolenum) runs a customized MIP search on a user provided problem (XPRSprob). The search is customized such that nodes are not cut-off by bounding and integer solution nodes are branched. The MIP solution enumerator marshals the solutions found to storage in a user provided MIP solution pool (XPRSmipsolpool).

In general the MIP solution enumerator is useful for generating a set of solutions for a problem. In particular, the MIP solution enumerator can be used to generate the n-best solutions to a problem. The user will typically be interested in such a set when there are constraints and/or costs not reflected in the problem and the user wants a set of solutions from which a final solution can be selected that best meets the external constraints and objective.
