Mixing polyhedra with two non divisible coefficients
We consider the mixed-integer set X = {(s, x, y) ∈ R × Z^n × Z^m : s + a1 x j ≥ bj , ∀ j ∈ N1, s + a2 y j ≥ dj, j ∈ N2} where N1 = {1,...,n}, N2 = {1,...,m} and a1, a2 ∈ Z_+\{0}. This set may arise in a relaxation of mixed-integer problems such as lot-sizing problems.We decompose X into a small numb...
