    ◆ SCIPincludeObjPresol()

    SCIP_RETCODE SCIPincludeObjPresol ( SCIP scip,
    scip::ObjPresol objpresol,
    SCIP_Bool  deleteobject 
    )

    creates the presolver for the given presolver 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) ); ... MyPresol* mypresol = new MyPresol(...); SCIP_CALL( SCIPincludeObjPresol(scip, &mypresol, FALSE) ); ... SCIP_CALL( SCIPfree(&scip) ); delete mypresol; // delete presol AFTER SCIPfree() !
    2. The object pointer is passed to SCIP and deleted by SCIP in the SCIPfree() call: SCIP_CALL( SCIPcreate(&scip) ); ... SCIP_CALL( SCIPincludeObjPresol(scip, new MyPresol(...), TRUE) ); ... SCIP_CALL( SCIPfree(&scip) ); // destructor of MyPresol is called here

    creates the presolver for the given presolver object and includes it in SCIP

    Parameters
    scipSCIP data structure
    objpresolpresolver object
    deleteobjectshould the presolver object be deleted when presolver is freed?
