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 |
