## A note on the MIR closure and basic relaxations of polyhedra

Anderson, Cornuejols and Li (2005) show that for a polyhedral mixed integer set defined by a constraint system Ax >= b, where x is n-dimensional, along with integrality restrictions on some of the variables, any split cut is in fact a split cut for a “basic relaxation”, i.e., one defined by a subset of linearly … Read more
