Antàalgorithmàis one of Swarm Intellingence algorithms that can be used to solve NP-Hard problems. The scheduling of courses and lecturers which are done routinely each semester can be solved by exact methods and heuristic methods. Each institution has its own constraints in arranging the schedule. This paper discusses a case study in STMIK Widya Dharma. The type of ant algorithm used is the Rank Base Ant System suitable for scheduling based on ranking, which is the lecturersââ¬â¢ priority level. The other parametersàare subjects, space, and time. It is expected that the software being analyzed withàAnt algorithms can provide solutions to the scheduling problem.àKeywords:ààuniversity timetable course,àAn algorithm, ASRank
