Function Documentation

SCIP_RETCODE SCIPincludeObjBranchrule	(	SCIP *	scip,
		scip::ObjBranchrule *	objbranchrule,
		SCIP_Bool	deleteobject
	)

creates the branching rule for the given branching rule object and includes it in SCIP

The method should be called in one of the following ways:

1. The user is resposible of deleting the object: SCIP_CALL( SCIPcreate(&scip) ); ... MyBranchrule* mybranchrule = new MyBranchrule(...); SCIP_CALL( SCIPincludeObjBranchrule(scip, &mybranchrule, FALSE) ); ... SCIP_CALL( SCIPfree(&scip) ); delete mybranchrule; // delete branchrule AFTER SCIPfree() !
2. The object pointer is passed to SCIP and deleted by SCIP in the SCIPfree() call: SCIP_CALL( SCIPcreate(&scip) ); ... SCIP_CALL( SCIPincludeObjBranchrule(scip, new MyBranchrule(...), TRUE) ); ... SCIP_CALL( SCIPfree(&scip) ); // destructor of MyBranchrule is called here

Parameters

scip	SCIP data structure
objbranchrule	branching rule object
deleteobject	should the branching rule object be deleted when branching rule is freed?

scip::ObjBranchrule* SCIPfindObjBranchrule	(	SCIP *	scip,
		const char *	name
	)

returns the branchrule object of the given name, or 0 if not existing

Parameters

scip	SCIP data structure
name	name of branching rule

scip::ObjBranchrule* SCIPgetObjBranchrule	(	SCIP *	scip,
		SCIP_BRANCHRULE *	branchrule
	)

returns the branchrule object for the given branching rule

Parameters

scip	SCIP data structure
branchrule	branching rule
