virtual void | resetModel (CbcModel *model) |
Resets stuff if model changes. | |
virtual void | setModel (CbcModel *model) |
update model (This is needed if cliques update matrix etc) | |
virtual int | solution (double &objectiveValue, double *newSolution) |
returns 0 if no solution, 1 if valid solution. | |

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.

double * | newSolution, | |||
