NEW YORK, May 28, 2008 – ACM's Special Interest Group on Algorithms and Computing Theory (SIGACT) has recognized the contribution of Daniel A. Spielman and ShangHua Teng for developing a rigorous framework to explain the practical success of algorithms on real data and real computers that could not be clearly understood through traditional techniques. Their technique, know as Smoothed Analysis, relies on deep mathematical analysis and insight. Since its appearance in 2001, it has been used as a basis for considerable research, confirming its importance to scientific computing. SIGACT and the European Association for Theoretical Computer Science (EATCS) will present the 2008 Gödel Prize for outstanding papers in theoretical computer science to Spielman and Teng at the International Colloquium on Automata, Languages, and Programming (ICALP) July 6 to 13, in Reykjavik, Iceland.
In a paper titled "Smoothed Analysis of Algorithms: Why the Simplex Algorithm Usually Takes Polynomial Time," the authors address a fundamental question of how algorithms function. Their research explains why the Simplex Algorithm, an important tool used by computers to solve a broad, basic class of optimization problems, works effectively in many practical areas, especially in business. It also represents a huge advance in addressing the grand challenge of predicting the performance of algorithms, which are clearly specified procedures guaranteed to give the correct answer, and heuristics, which are methods of solving problems through intelligent trial and error.
Understanding the mathematical structure of these problems is necessary to designing efficient algorithms and software. The findings of Spielman and Teng were published in the Journal of the ACM in 2004.
Daniel Spielman, professor of applied mathematics and computer science at Yale University, previously taught at Massachusetts Institute of Technology (MIT), and completed his postdoctoral work in mathematical sciences at the University of California Berkeley. He was awarded the ACM Doctoral Dissertation Award in 1995, and was honored with the Best Student Paper award at the ACM Symposium on Theory of Computing in both 1994 and 1995. A graduate of Yale with a BA degree and the winner of the Beckwith Prize in mathematics, Spielman received a Ph.D. degree in mathematics from MIT.
ShangHua Teng is a professor of computer science at Boston University and senior research scientist at Akamai Technologies, Inc. He is also visiting professor at Tsinghua University in Beijing, China, visiting professor at Microsoft Research Asia, and affiliated research professor of mathematics at MIT. Prior to joining Boston University, he was associate professor at the University of Illinois at UrbanaChampaign; assistant professor of computer science at the University of Minnesota; and instructor of mathematics at MIT. He obtained a postdoctoral position at Xerox Palo Alto Research Center (PARC) where he began an active participation with industry and collaboration with engineers and scientists in developing realworld products. Teng received dual B.S. degrees in computer science and electrical engineering from Shanghai JiaoTong University, and an MS degree in computer science from the University of Southern California. He was awarded a Ph.D. degree in computer science from Carnegie Mellon University.
The Gödel Prize, which includes an award of $5,000, is named in honor of Kurt Gödel, who was born in AustriaHungary (now the Czech Republic) in 1906. Gödel's work has had immense impact upon scientific and philosophical thinking in the 20^{th} century. The award recognizes his major contributions to mathematical logic and the foundations of computer science.
