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() !
  2. 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
scipSCIP data structure
objpricervariable pricer object
deleteobjectshould the pricer object be deleted when pricer is freed?
