Aaron Abrams and Skip Garibaldi, “Finding Good Bets in the Lottery, and Why You Shouldn’t Take Them”, American Mathematical Monthly, 117 (2010), no. 1, 3-26.

Lottery operators make money – lots of it apparently – so on average, players must lose money. But does this apply to rolling jackpots, where winnings can reach staggering amounts? (Rolling jackpots are those games in which prize money is rolled over from one game to the next when no one wins the jackpot.) Does there come a time when playing such a lottery makes a good bet? If so, when is that? And does that make playing a good investment?

After constructing a model of a rolling jackpot lottery, the authors of this paper consider these questions. They develop an analysis of rate of return, from which they draw their conclusions regarding bets. Two outstanding features of this work are the incorporation of concrete lotteries as examples and the mathematics (mostly elementary calculus) and statistics used. They do not end their analysis at bets however, but go on to explore the less familiar (to most readers) territory of investments. This necessitates considering risk. And so, economics and subsequently linear algebra get involved. This supports their conclusion that lotteries will almost never be good investments.

The subject matter, the mathematics used, the examples, and the conclusions, but especially the presentation of the material, all combine to make “Finding Good Bets” an exceptional article.

ACM Special Interest Group on Information Retrieval (SIGIR) “Best Paper” Award
Published Date: 2011-08-08
This year's ACM Special Interest Group on Information Retrieval (SIGIR) annual conference best paper award was presented to Mikhail Ageev (Moscow State University), and Qi Guo, Dmitry Lagun, and Eugene Agichtein (Emory University), for their paper "Find It If You Can: A Game for Modeling Different Types of Web Search Success Using Interaction Data". The paper, written while Mikhail was visiting the IR Lab at Emory, proposes a principled formalization of different types of success for informational search, and it presents a scalable game-like infrastructure for crowdsourcing search behavior studies. The SIGIR annual conference is the premier conference in information retrieval. This year, the rate of acceptance for submitted papers was 19.8%. More details on the conference and award can be found on the SIGIR website:

Ken Ono to give the American Mathematical Society's 2012 Erdos Memorial Lecture.
Published Date: 2011-02-21
Ken Ono, Asa Griggs Candler Professor of Mathematics, has been selected to give the American Mathematical Society's 2012 Erdos Memorial Lecture. The lecture is an annual invited address made possible by a fund created by Andrew Beal, a Dallas banker and mathematical enthusiast. It is named for the mathematician Paul Erdös. The Beal Prize Fund ($100,000) is being held by the AMS until it is awarded for a correct solution to the Beal Conjecture. In the meantime, the interest from this fund is used to support the Erdös Memorial Lecture. The Erdos Lectures are one the most prestigious endowed invited addresses hosted by the American Mathematical Society. Previous speakers include Ron Graham, John Conway, Hillel Furstenberg, Avi Wigderson, Bernd Sturmfels, Persi Diaconis, Bela Bollobas, Andrew Granville, W. Timothy Gowers and Jeffrey C. Lagarias.

The Department of Mathematics and Computer Science is pleased to host the 3rd edition of The Georgia Scientific Computing (GSC) Symposium on Saturday, February 12, 2011. The purpose of the GSC Symposium is to provide an opportunity for professors, postdocs, and graduate students in the Atlanta area to meet in an informal setting, to exchange ideas, and to highlight local scientific computing research. However, it is open to the whole research community.

The symposium will include seven invited talks, a poster session, and substantial time for interaction among the participants. The invited speakers include:

- Alfio Quarteroni, École Polytechnique Fédérale de Lausanne, Politecnico di Milano
- Jim Nagy, Emory University
- Allen Tannenbaum, Georgia Institute of Technology
- George Biros, Georgia Institute of Technology
- Hao-min Zhou, Georgia Institute of Technology
- Vladimir Bondarenko, Georgia State University
- Thiab Taha, University of Georgia
