Abstract
Recently, Guan, Pan, and Zohu presented a MIP model for the thermal single-unit commitment claiming that provides an integer feasible solution for any convex cost function. In this note we provide a counterexample to this statement and we produce evindence that the perspective function is needed for this aim.File in questo prodotto:
