Perspective cuts for 0-1 mixed integer programs

ABSTRACT

We show that the convex envelope of the objective function of a Mixed-Integer Programming problem is the perspective function of the continuous part of the objective function. Using a characterization of the subdifferential of the perspective function we derive a family of valid in- equalities that can be used to substantially improve the performances of an enumerative (Branch & Bound) approach for at least one particular model with the required structure, the Unit Com- mitment problem in electrical power production.
