Member Function Documentation

virtual CbcHeuristic* CbcHeuristicCrossover::clone (  )  const [virtual]

Clone.

Implements CbcHeuristic.

CbcHeuristicCrossover& CbcHeuristicCrossover::operator= ( const CbcHeuristicCrossover rhs  ) 

Assignment operator.

virtual void CbcHeuristicCrossover::generateCpp ( FILE *  fp  )  [virtual]

Create C++ lines to get to current state.

Reimplemented from CbcHeuristic.

virtual void CbcHeuristicCrossover::resetModel ( CbcModel model  )  [virtual]

Resets stuff if model changes.

Implements CbcHeuristic.

virtual void CbcHeuristicCrossover::setModel ( CbcModel model  )  [virtual]

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

Reimplemented from CbcHeuristic.

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

returns 0 if no solution, 1 if valid solution.

Fix variables if agree in useNumber_ solutions when_ 0 off, 1 only at new solutions, 2 also every now and then add 10 to make only if agree at lower bound

Implements CbcHeuristic.

void CbcHeuristicCrossover::setNumberSolutions ( int  value  )  [inline]

Sets number of solutions to use.
