Preface to the proceedings

Abstract

This Special Part of the ANZIAM Journal (supplement) contains the refereed papers from the tenth Biennial Computation Techniques and Applications Conference (CTAC2001) held at the University of Queensland, Brisbane, during 16-18 July 2001. The CTAC series of conferences is held under the auspices of the Computational Mathematics Group of the Australian and New Zealand Industrial and Applied Mathematics (ANZIAM) division of the Australian Mathematics Society. They provide a forum for scientists, engineers, and mathematicians interested in the development of computational techniques and their application to problems of practical importance. Previous conferences in the CTAC series have been held at University of Sydney (1983), University of Melbourne (1985), University of Sydney (1987), Griffith University, Brisbane (1989), University of Adelaide (1991), Australian National University, Canberra (1993), Swinburne University of Technology, Melbourne (1995), University of Adelaide (1997), Australian National University, Canberra (1999). There were about 100 participants at the conference, five of whom gave keynote addresses as part of the general program for CTAC2001-these speakers and the titles of their presentations were:

Real Time Optimisation and Nonlinear Model Predictive Control for Large DAE Models

Prof Hans-Georg Bock, Interdisciplinary Center for Scientific Computing (IWR), Heidelberg, Germany;

Some Computational Problems Arising in Continuous Time Finance

Prof Carl Chiarella, School of Finance and Economics, University of Technology, Sydney, Australia;

Matrix Decomposition Algorithms in Finite Element Methods for Poisson's Equation

Prof Graeme Fairweather, Mathematical and Computer Sciences, Colorado School of Mines, Golden, USA.

Computational Problems in Landscape Design for Conservation

Prof Hugh Possingham, Departments of Zoology and Mathematics, University of Queensland, Brisbane, Australia;

Iterative Methods for Nonsymmetric Ill-posed Problems

Prof Lothar Reichel, Kent State University, Ohio, USA;

In addition to these invited presentations, 74 contributed papers were presented at the conference. Of these, 48 were submitted for consideration for the CTAC2001 Proceedings, and 43 were accepted for publication after each was peer-reviewed by at least two referees and the papers revised to the satisfaction of the referees. Following the convention established in previous CTAC proceedings, the papers appearing here have not been grouped by topic; the abstracts of the five invited speakers are included, followed by the contributed papers in alphabetical order of the first author. As with previous CTAC Proceedings, the papers cover a wide variety of topics with the usual CTAC emphasis on both industrial applications and numerical techniques. A new feature is the marked number of presentations in the areas of financial mathematics and computational biology. The editors thank the referees for their time and assistance with the refereeing process, and the ANZIAM Journal of the (supplement) for agreeing to publish the proceedings as a journal special issue. Also, the editors would like to especially acknowledge the hard work of the Organising Committee and in addition, Jerard Barry, Markus Hegland and Yvette Zuidema. CTAC2001 Organising Committee
