SCIPincludeObjHeur()

SCIP_RETCODE SCIPincludeObjHeur	(	SCIP *	scip,

creates the primal heuristic for the given primal heuristic object and includes it in SCIP

Parameters

scip	SCIP data structure
objheur	primal heuristic object
deleteobject	should the primal heuristic object be deleted when heuristic is freed?
