## Member Function Documentation

virtual CbcHeuristic* CbcHeuristicVND::clone | ( |  | ) | const`[virtual]`

Clone.

Implements CbcHeuristic.

CbcHeuristicVND& CbcHeuristicVND::operator= | ( | const CbcHeuristicVND & | rhs | ) |

Assignment operator.

Reimplemented from CbcHeuristic.

virtual void CbcHeuristicVND::generateCpp | ( | FILE * | fp | ) | `[virtual]`

Create C++ lines to get to current state.

Reimplemented from CbcHeuristic.

virtual void CbcHeuristicVND::resetModel | ( | CbcModel * | model | ) | `[virtual]`

Resets stuff if model changes.

Implements CbcHeuristic.

virtual void CbcHeuristicVND::setModel | ( | CbcModel * | model | ) | `[virtual]`

update model (This is needed if cliques update matrix etc)

Reimplemented from CbcHeuristic.

virtual int CbcHeuristicVND::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.

int CbcHeuristicVND::solutionFix | ( | double & | objectiveValue,
|  | double * | newSolution,
|  | const int * | keep |
| ) |  |  |

This version fixes stuff and does IP.

void CbcHeuristicVND::setHowOften | ( | int | value | ) | `[inline]`

Sets how often to do it.

Definition at line 63 of file CbcHeuristicVND.hpp.

double* CbcHeuristicVND::baseSolution | ( |  | ) | const`[inline]`

base solution array so we can set

Definition at line 67 of file CbcHeuristicVND.hpp.
