NEWS from the PRESIDENT
Perhaps the most mathematically significant thing happening in Australia recently is the establishment of its own Australian Mathematical Sciences Institute, AMSI. See http://www.amsi.org.au/ for details (but this is so new, you won't find too much there).
One thing which is firmly planned right now by AMSI is a set of summer courses for honours and postgraduate students.
Another is the call for expressions of interest for symposia/workshops for the year 2003.
Approximately in the words of the Interim Director, Tony Guttmann, this Institute has a more ambitious scope than its overseas counterparts, with (down to) a fifth or tenth of the funding ... not sure if he is referring to the NZ institute here. Our Canadian members probably get the idea quite accurately though.
Let me close by hoping that as many of you as possible can make it to Newcastle in December for the 27 ACCMCC.
Nick Wormald CMSA President
RECENT CONFERENCE REPORTS
AWOCA 2002 Australasian Workshop on Combinatorial Algorithms, 6-10 JULY 2002.
The Thirteenth Australasian Workshop on Combinatorial Algorithms (AWOCA) was held on Fraser Island, Queensland, from 7th to 10th July in the very peaceful surrounds of Kingfisher Bay Resort.
Participants enjoyed lavish lunches, picturesque sunsets, an excursion to the exquisite white sand, pure freshwater lakes, and some karaoke at the conference dinner. The only unfortunate event (apart from some of the karaoke acts) was a collision between a cow and a University of Queensland vehicle on the return trip to Brisbane. Thankfully the cow was the only fatality; the only injured person was driver Peter Adams who spent the night in Gympie hospital and suffered a badly mangled broken toe. But we were all extremely grateful Peter had ensured that we were wearing seatbelts.
The invited speakers were:
* Curt Lindner, Auburn University, USA A brief history of the embedding of partial 4-cycle systems * Kunsoo Park, Seoul National University, Korea Parallel Algorithms for Dictionary Operations on Balanced Search Trees * Chris Rodger, Auburn University, USA Edge-colorings, hamilton cycles and graph decompositions * Heather Gavlas, University of Vermont, USA Hamiltonian Paths in Cartesian Powers of Directed Cycles * Edy Tri Baskoro, ITB, Indonesia On the graph Ramsey Numbers R(G,Wm) * Frantisek Franek, MacMaster University, Canada Computing quasi suffix arrays
A special thank-you to the School of Physical Sciences at the University of Queensland, the EPSA Faculty at UQ, and the ICA for their sponsorship, and a very special thank-you to Diane Donovan who was the chief organiser. Photos from the conference are available from the website: www.maths.uq.edu.au/~njc/awoca/awoca2002 [Scroll up a bit if you click on "Photos" at that site! Ed.]
DISCRETE MATHEMATICS SESSION within the 46th AustMS Meeting, Newcastle, 30 SEPT - 3 OCT 2002.
Ten talks were presented in the Special Session on Discrete Mathematics at the recent Australian Mathematical Society's Annual Meeting in Newcastle. These were presented by:
* Lynn Batten Blocking semiovals of type (1,m+1,n+1) * Diana Combe Magic labellings of graphs over abelian groups * Peter Eades How to make a symmetric drawing of a graph * Henning Fernau Using graph theory to design parameterized algorithms * John Galati Affine planar maps and quasiregular collineation groups of finite projective planes * Alain LeBel Shift actions on cocycles: a case study * Jim MacDougall Magic labelings of graphs * Bill Palmer Bhaskar Rao designs and the groups of order 12 * Rinovia Simanjuntak A Moore bound for graphs embedded in surfaces * Martin Sutton A real-world database problem for discrete mathematicians
At the conference dinner the following was circulated on some tables:
Uncle Ebenezer is dying. He has exactly 500 gold pieces, all of which he distributes amongst his four nephews, Abraham, Bob, Cecil and Dwayne. Each nephew gets his share in a little bag. They do not know what the others got, but they do know:
1. That everybody got more tha 100 pieces. 2. That Cecil and Dwayne got an equal number of pieces. 3. Abe's and Bob's shares are different from Cecil and Dwayne. 4. Abe's share is not the same as Bob's.
Each nephew counts out his share in secret. Then Cecil says to Bob: "Did you get a perfect square?" Bob does not answer truthfully. (You are not told whether his answer was "yes" or "no".) Cecil believes Bob, and on the basis of Bob's answer concludes that Bob got the most. Abraham, sitting by, smiles to himself because he has deduced that Bob lied. How many pieces did each nephew get?
(There is a solution, and only one solution. There is enough information to solve the problem. There are no tricks. No mathematical ability is called for beyond knowledge of which numbers are perfect squares. A solution depends on logical thinking and some psychological insight.)
FUTURE WORKSHOP AND CONFERENCE ANNOUNCEMENTS: Victoria Algebra Days Deakin University, Victoria, Australia, 28-29 OCT 2002.

RECENT NEWS OF CMSA MEMBERS and others:
Peter Adams, Darryn Bryant and Jonathan Keith
(all from the Department of Mathematics at UQ) and Keith Mitchelson (from the Australian Genome Research Facility at UQ) have received a $250,000 grant from the Biotechnology Innovation Fund (BIF). This is the maximum size for BIF grants, and the money will be used to fund research, development and commercialisation of a novel DNA sequencing technology. The spin-out company Combinomics is being formed, to undertake the development. BIF is funded by the Federal Government, and is a merit-based competitive grants program which aims to increase the rate of commercialisation of Australian biotechnology discoveries. It provides funding assistance to companies to demonstrate proof-of-concept between the research and commercialisation stages.
News from Ian Roberts (Northern Territory University when he's not travelling!), who writes:
I am currently on a long-deserved and long-needed sabbatical (or PDL - professional development leave in NTU speak). My itinery is roughly:
San Diego State (David Carlson) 4-13/9, University of Wisconsin (Sergei Bezrukov) 13-27/9, MIGHTY - Mid West Graph Theory Conference at Illinois State at Bloomington-Normal (Roger Eggleton), Southern Illinois University 28-2/10 (Wal Wallis), South Carolina (Jerry Griggs) till 22/10 with a quick trip to Clemson for a conference 10-11/10, Reading (Tony Hilton) (UK) till 2/11, Bielefeld, Rostock (Uwe Leck) and Magdeburg in Germany 2-16/11, then Nottingham (Neville Davies)(UK) and home before the end of November.
See you all at 27ACCMCC in Newcastle.
The trip has been good so far, with lots of new problems and ideas and even some solutions. Round-the-world fares are a good way to go. Jeanette McLeod is teaching my first year class in discrete maths while I'm away and Prabhu Manyem at the University of South Australia is helping out with a third level subject from his place with Jeanette as local tutor.
Richard Bean writes from Iran:
I am working as a post-doctoral researcher in combinatorics at the Institute for Studies in Theoretical Physics and Mathematics in Tehran, Iran. This position is a two year position.
I have done some more work on the largest size of critical sets in Latin squares, and am learning about graph embedding problems and chess related problems (the latter for fun).
Richard Bean was recently awarded his PhD from the University of Queensland, with Diane Donovan as supervisor.

Information from Rebecca Gower and job information at Linz
Rebecca Gower is working at a firm in Oxford, and she writes:
Don't know if this is of any interest to put in the CMSA newsletter. It was sent to me but I don't really know academics and graduates looking for jobs so perhaps the newsletter would reach those people?
Have just got back from a week's holiday in Ireland and I am just trying to catch up with emails and what needs attention now. The holiday was great - amazingly sunny and lovely for the time of year.
