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

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