Summary
In this note we present new properties of cliques induced constraints straintsX(C +r )-X(C -r ) ≤ 1 - |C -r | for λ εS, whereS is the set of cliques that are implied by 0–1 mixed integer programs. These properties allow to further fixing of 0–1 variables, to detect instance's infeasibility and to imply new cliques.
