Australasian Computer Science Week 3-7 February 1997, Macquarie University, Sydney, Australia ACSC'97, CATS'97, and ACAC'97 Call for Papers ACSC'97 - Twentieth Australasian Computer Science Conference 5-7 February 1997 ACSC'97 is the major Australasian computer science conference and is now in its twentieth year. The conference has a high reputation for the quality of the research presented, ranging from theory and experiment to practice and application. Submissions are now invited for ACSC'97. We welcome papers describing original contributions in all fields of Computer Science research and education. Each paper will be judged on its originality, significance, correctness, and clarity. Its contribution should be clearly explained in both general and technical terms, and authors should make every effort to ensure that its technical content is understandable by a broad audience. Submission of a paper should be regarded as an undertaking that, should the paper be accepted, at least one of the authors will attend the conference to present the work. Submitted papers should be no longer than 6,000 words. To be considered, four printed copies must reach the address below by the submission date (15 August 1996), which is a hard deadline.
