Constantinos Daskalakis, an assistant professor in MIT`s Computer Science and Artificial Intelligence Laboratory, has exported those techniques to game theory, a branch of mathematics with applications in economics, traffic management -- on both the Internet and the interstate -- and biology, among other things. By showing that some common game-theoretical problems are so hard that they`d take the lifetime of the universe to solve, Daskalakis is suggesting that they can`t accurately represent what happens in the real world. http://www.physorg.com/news176978473.html Technology - Computer Sciences Mon, 09 Nov 2009 09:20:01 EST news176978473
