virtual CbcHeuristic* CbcHeuristicRINS::clone

(

)

const [virtual]

Clone.

Implements CbcHeuristic.

CbcHeuristicRINS& CbcHeuristicRINS::operator=

(

const CbcHeuristicRINS &

rhs

)

Assignment operator.

Reimplemented from CbcHeuristic.

virtual void CbcHeuristicRINS::generateCpp

model

)

[virtual]

Resets stuff if model changes.

Implements CbcHeuristic.

virtual void CbcHeuristicRINS::setModel

(

CbcModel *

model

)

[virtual]

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

Reimplemented from CbcHeuristic.

virtual int CbcHeuristicRINS::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 CbcHeuristicRINS::solutionFix	(	double &	objectiveValue,
		double *	newSolution,
		const int *	keep
	)

This version fixes stuff and does IP.
