virtual void AbcHeuristic::setModel ( AbcModel model) [virtual]

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

Reimplemented in AbcRounding, and AbcRounding.

virtual AbcHeuristic* AbcHeuristic::clone ( ) const [pure virtual]

Clone.

Implemented in AbcRounding, and AbcRounding.

virtual int AbcHeuristic::solution ( double &  objectiveValue,
double *  newSolution 
) [pure virtual]

returns 0 if no solution, 1 if valid solution with better objective value than one passed in Sets solution values if good, sets objective value This is called after cuts have been added - so can not add cuts

Implemented in AbcRounding, and AbcRounding.

virtual int AbcHeuristic::solution ( double &  objectiveValue,
