cuttingplane

Cutting plane-based GDP reformulation.

Implements a general cutting plane-based reformulation for linear and convex GDPs.

Classes

CuttingPlane_Transformation()

Relax convex disjunctive model by forming the bigm relaxation and then iteratively adding cuts from the hull relaxation (or the hull relaxation after some basic steps) in order to strengthen the formulation.

Functions

back_off_constraint_by_fixed_tolerance(cut, ...)	Makes cut more conservative by absolute tolerance TOL
back_off_constraint_with_calculated_cut_violation(...)	Calculates the maximum violation of cut subject to the relaxed hull constraints.
create_cuts_fme(transBlock_rHull, var_info, ...)	Returns a cut which removes x* from the relaxed bigm feasible region.
create_cuts_normal_vector(transBlock_rHull, ...)	Returns a cut which removes x* from the relaxed bigm feasible region.
do_not_tighten(m)
