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

creates the variable pricer for the given variable pricer object and includes it in SCIP

Parameters

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