Preface
We are pleased to present this LNCS volume, the Proceedings of the 22nd Australasian Joint Conference on Artificial Intelligence (AI 2009), held in Melbourne, Australia, December 1–4, 2009. This long established annual regional conference is a forum both for the presentation of research advances in artificial intelligence and for scientific interchange amongst researchers and practitioners in the field of artificial intelligence. Conference attendees were also able to enjoy AI 2009 being co-located with the Australasian Data Mining Conference (AusDM 2009) and the 4th Australian Conference on Artificial Life (ACAL 2009). This year AI 2009 received 174 submissions, from authors of 30 different countries. After an extensive peer review process where each submitted paper was rigorously reviewed by at least 2 (and in most cases 3) independent reviewers, the best 68 papers were selected by the senior Program Committee for oral presentation at the conference an
