Constructor & Destructor Documentation

CglFakeClique::CglFakeClique

(

const CglFakeClique &

rhs

)

Copy constructor.

CglFakeClique::CglFakeClique	(	OsiSolverInterface *	solver = NULL,
		bool	setPacking = false
	)

Default constructor.

If the setPacking argument is set to true then CglFakeClique will assume that the problem in the solverinterface passed to the generateCuts() method describes a set packing problem, i.e.,

• all variables are binary
• the matrix is a 0-1 matrix
• all constraints are '= 1' or '<= 1'

Otherwise the user can use the considerRows() method to set the list of clique rows, that is,

• all coeffs corresponding to binary variables at fractional level is 1
• all other coeffs are non-negative
• the constraint is '= 1' or '<= 1'.

If the user does not set the list of clique rows then CglFakeClique will start the generateCuts() methods by scanning the matrix for them.

const [virtual]

Clone.

Reimplemented from CglClique.

CglFakeClique& CglFakeClique::operator=

(

const CglFakeClique &

rhs

)

Assignment operator.

virtual void CglFakeClique::generateCuts	(	const OsiSolverInterface &	si,
		OsiCuts &	cs,
		const CglTreeInfo	info = CglTreeInfo()
	)			const [virtual]

Generate cuts for the model data contained in si.

The generated cuts are inserted into and returned in the collection of cuts cs.

Reimplemented from CglClique.

void CglFakeClique::assignSolver

(

OsiSolverInterface *

fakeSolver

)

Assign solver (generator takes over ownership).
