31 * We separate disjunctive cuts for two term disjunctions of the form \f$x_1 = 0 \vee x_2 = 0\f$. They can be generated
32 * directly from the simplex tableau. For further information, we refer to@n
33 * "A complementarity-based partitioning and disjunctive cut algorithm for mathematical programming problems with
34 * equilibrium constraints"@n

36 *
37 * Cut coefficients belonging to integer variables can be strengthened by the 'monoidal cut strengthening' procedure, see@n
38 * "Strengthening cuts for mixed integer programs"@n
