Policy for keeping cuts. | |
CutsTypes | type_ |
Type of cuts. | |
unsigned int | cut_count_ |
Count the total number of cuts generated. | |
unsigned int | maximum_oa_cuts_ |
maximum number of OA cuts. | |
![]() | |
OsiTMINLPInterface * | nlp_ |
Pointer to nlp interface. | |
BabSetupBase * | s_ |
Pointer to setup. | |
int | nSolve_ |
Number of nlp solved done. | |
OsiSolverInterface * | lp_ |
A linear solver. | |
OsiObject ** | objects_ |
Some objects the feasiblitiy of which to verify. | |
int | nObjects_ |
Number of objects.*/. | |
int | nLocalSearch_ |
number of local searches performed | |
CoinMessageHandler * | handler_ |
messages handler. | |
CoinMessages | messages_ |
Messages for OA. | |
bool | leaveSiUnchanged_ |
Wether or not we should remove cuts at the end of the procedure. | |
bool | reassignLpsolver_ |
Do we need to reassign the lp solver with Cbc. | |
double | timeBegin_ |
time of construction | |
int | numSols_ |
number of solutions found by OA_decomposition. | |
Parameters | parameters_ |
Parameters. | |
OsiCuts | savedCuts_ |
Saved cuts: in some cases when using OA to check feasible solution algorithm may loop because Cbc removes inactive cuts. | |
int | currentNodeNumber_ |
Store the current node number. | |
