Function Documentation

SCIPincludeObjBranchrule()

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

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

Parameters

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