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 A researcher of the University of Granada, Spain, has designed a new system for the mobility of military troops within a battlefield based on the mechanisms used by ant colonies to move using a commercial videogame. http://www.physorg.com/news176726947.html Technology - Computer Sciences Fri, 06 Nov 2009 11:00:02 EST news176726947 (PhysOrg.com) -- Dartmouth Computer Scientist Hany Farid has new evidence regarding a photograph of accused John F.
