double | away |
A variable have to be at least away from integrity to be generated. | |
double | timeLimit |
Total time limit for cut generation. | |
double | singleCutTimeLimit |
Time limit for generating a single cut. | |
double | rhsWeight |
Weight to put in RHS of normalization if static. | |
Flags | |
bool | useTableauRow |
Do we use tableau row or the disjunction (I don't really get that there should be a way to always use the tableau). | |
bool | modularize |
Do we apply Egon Balas's Heuristic for modularized cuts. | |
bool | strengthen |
Do we strengthen the final cut (always do if modularize is 1). | |
bool | countMistakenRc |
Wether to limit or not the number of mistaken RC (when perturbation is applied). | |
SeparationSpaces | sepSpace |
Work in the reduced space (only non-structurals enter the basis). | |
bool | perturb |
Apply perturbation procedure. | |
Normalization | normalization |
How to weight normalization. | |
RhsWeightType | rhsWeightType |
How to weight RHS of normalization. | |
LHSnorm | lhs_norm |
How to weight LHS of normalization. | |
ExtraCutsMode | generateExtraCuts |
Generate extra constraints from optimal lift-and-project basis. | |
