Function Documentation

SCIP_RETCODE SCIPincludeObjSepa	(	SCIP *	scip,
		scip::ObjSepa *	objsepa,
		SCIP_Bool	deleteobject
	)

creates the cut separator for the given cut separator 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) ); ... MySepa* mysepa = new MySepa(...); SCIP_CALL( SCIPincludeObjSepa(scip, &mysepa, FALSE) ); ... SCIP_CALL( SCIPfree(&scip) ); delete mysepa; // delete sepa AFTER SCIPfree() !

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

creates the cut separator for the given cut separator object and includes it in SCIP

Parameters

scip	SCIP data structure
objsepa	cut separator object
deleteobject	should the cut separator object be deleted when cut separator is freed?
