## Member Function Documentation

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

Clone.

Implements CbcHeuristic.

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

Assignment operator.

Reimplemented from CbcHeuristic.

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

Create C++ lines to get to current state.

Reimplemented from CbcHeuristic.

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

Resets stuff if model changes.

Implements CbcHeuristic.

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

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

Reimplemented from CbcHeuristic.

virtual int CbcHeuristicLocal::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 is called after cuts have been added - so can not add cuts First tries setting a variable to better value. If feasible then tries setting others. If not feasible then tries swaps

This first version does not do LP's and does swaps of two integer variables. Later versions could do Lps.

Implements CbcHeuristic.

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

This version fixes stuff and does IP.

void CbcHeuristicLocal::setSearchType | ( | int | value | ) | `[inline]`

Sets type of search.

Definition at line 65 of file CbcHeuristicLocal.hpp.

int* CbcHeuristicLocal::used | ( |  | ) | const`[inline]`

Used array so we can set.
