Member Function Documentation
| virtual CbcHeuristic* CbcHeuristicRINS::clone | ( | ) | const [virtual] |
Clone.
Implements CbcHeuristic.
| CbcHeuristicRINS& CbcHeuristicRINS::operator= | ( | const CbcHeuristicRINS & | rhs | ) |
Assignment operator.
Reimplemented from CbcHeuristic.
| virtual void CbcHeuristicRINS::generateCpp | ( | FILE * | fp | ) | [virtual] |
Create C++ lines to get to current state.
Reimplemented from CbcHeuristic.
| virtual void CbcHeuristicRINS::resetModel | ( | CbcModel * | model | ) | [virtual] |
Resets stuff if model changes.
Implements CbcHeuristic.
| virtual void CbcHeuristicRINS::setModel | ( | CbcModel * | model | ) | [virtual] |
update model (This is needed if cliques update matrix etc)
Reimplemented from CbcHeuristic.
| virtual int CbcHeuristicRINS::solution | ( | double & | objectiveValue, | |
| double * | newSolution | |||
| ) | [virtual] |
returns 0 if no solution, 1 if valid solution.
Sets solution values if good, sets objective value (only if good) This does Relaxation Induced Neighborhood Search
Implements CbcHeuristic.

| double * | newSolution, | |||
| const int * | keep | |||
| ) |
This version fixes stuff and does IP.
