This paper proposes an ant colony optimization hybrid heuristic (ACH) for the total earliness tardiness single machine scheduling problem where jobs have different processing times and distinct due dates, and the machine can not be idle. ACH is an ant colony system with daemon actions that intensify the search around good quality solutions. The computational results show the effectiveness of ACH.
