Detailed Description

disjunctive cut separator

We separate disjunctive cuts for two term disjunctions of the form $$x_1 = 0 \vee x_2 = 0$$. They can be generated directly from the simplex tableau. For further information, we refer to
"A complementarity-based partitioning and disjunctive cut algorithm for mathematical programming problems with equilibrium constraints"
Júdice, J.J., Sherali, H.D., Ribeiro, I.M., Faustino, A.M., Journal of Global Optimization 36(1), 89–114 (2006)

Cut coefficients belonging to integer variables can be strengthened by the 'monoidal cut strengthening' procedure, see
"Strengthening cuts for mixed integer programs"
