Functions
SCIP_RETCODE	SCIPcreateObjProb (SCIP *scip, const char *name, scip::ObjProbData *objprobdata, SCIP_Bool deleteobject)

Function Documentation

SCIP_RETCODE SCIPcreateObjProb	(	SCIP *	scip,
		const char *	name,
		scip::ObjProbData *	objprobdata,
		SCIP_Bool	deleteobject
	)

creates empty problem, initializes all solving data structures, and sets the user problem data to point to the given user data object

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

1. The user is resposible of deleting the object: SCIP_CALL( SCIPcreate(&scip) ); ... MyProbData* myprobdata = new MyProbData(...); SCIP_CALL( SCIPcreateObjProb(scip, "probname", &myprobdata, FALSE) ); ... // solve the problem SCIP_CALL( SCIPfreeProb(scip) ); delete myprobdata; // delete probdata AFTER SCIPfreeProb() ! ... SCIP_CALL( SCIPfree(&scip) );
2. The object pointer is passed to SCIP and deleted by SCIP in the SCIPfreeProb() call: SCIP_CALL( SCIPcreate(&scip) ); ... SCIP_CALL( SCIPcreateObjProb(scip, "probname", new MyProbData(...), TRUE) ); ... SCIP_CALL( SCIPfree(&scip) ); // problem is freed and destructor of MyProbData is called here

Parameters

scip	SCIP data structure
name	problem name
objprobdata	user problem data object
deleteobject	should the user problem data object be deleted when problem is freed?

scip::ObjProbData* SCIPgetObjProbData

(

SCIP *

scip

)

gets user problem data object Warning! This method should only be called after a problem was created with SCIPcreateObjProb(). Otherwise, a segmentation fault may arise, or an undefined pointer is returned.

Parameters

scip	SCIP data structure
