Function Documentation

SCIP_RETCODE SCIPincludeObjPricer	(	SCIP *	scip,
		scip::ObjPricer *	objpricer,
		SCIP_Bool	deleteobject
	)

creates the variable pricer for the given variable pricer 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) ); ... MyPricer* mypricer = new MyPricer(...); SCIP_CALL( SCIPincludeObjPricer(scip, &mypricer, FALSE) ); ... SCIP_CALL( SCIPfree(&scip) ); delete mypricer; // delete pricer AFTER SCIPfree() !

1. The object pointer is passed to SCIP and deleted by SCIP in the SCIPfree() call: SCIP_CALL( SCIPcreate(&scip) ); ... SCIP_CALL( SCIPincludeObjPricer(scip, new MyPricer(...), TRUE) ); ... SCIP_CALL( SCIPfree(&scip) ); // destructor of MyPricer is called here

Parameters

scip	SCIP data structure
objpricer	variable pricer object
deleteobject	should the pricer object be deleted when pricer is freed?

scip::ObjPricer* SCIPfindObjPricer	(	SCIP *	scip,
		const char *	name
	)

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

Parameters

scip	SCIP data structure
name	name of variable pricer

scip::ObjPricer* SCIPgetObjPricer	(	SCIP *	scip,
		SCIP_PRICER *	pricer
	)

returns the variable pricer object for the given pricer

Parameters

scip	SCIP data structure
pricer	pricer
