FICO Xpress Optimization Examples Repository

Collecting all solutions with the MIP solution pool

Description

We take the power generation problem stored in hpw15.mps which seeks to optimise the operating pattern of a group of electricity generators. We solve the problem collecting all solutions found during the MIP search. The optimal solution's objective and solution values are printed to screen.
