Member Function Documentation

virtual CbcHeuristic* CbcHeuristicVND::clone

(

)

const [virtual]

Clone.

Implements CbcHeuristic.

CbcHeuristicVND& CbcHeuristicVND::operator=

(

const CbcHeuristicVND &

rhs

)

Assignment operator.

Reimplemented from CbcHeuristic.

virtual void CbcHeuristicVND::generateCpp

(

FILE *

fp

)

[virtual]

Create C++ lines to get to current state.

Reimplemented from CbcHeuristic.

virtual void CbcHeuristicVND::resetModel

CbcModel *

model

)

[virtual]

Resets stuff if model changes.

Implements CbcHeuristic.

virtual void CbcHeuristicVND::setModel

(

CbcModel *

model

)

[virtual]

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

Reimplemented from CbcHeuristic.

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

This version fixes stuff and does IP.

void CbcHeuristicVND::setHowOften

(

int

value

)

[inline]

Sets how often to do it.

Definition at line 63 of file CbcHeuristicVND.hpp.

double* CbcHeuristicVND::baseSolution

(

)

const [inline]

base solution array so we can set
