Stephan Schulz writes "Today, the CADE ATP System Competition will pit about 20 of the worlds most powerful mechanical mathematicians against each other — and for the first time they can win not only honour, but a monetary prize. The systems will reason against the clock on tasks ranging from undergraduate math problems and Cluedo-like puzzles to figuring out the possible responsibility for terrorist attacks from giant knowledge bases. If you think that is not impressive enough, they are doing it at a rate of 12 problems per hour, all day long. The competition starts at 10 a.m. in Sydney, Australia, which is midnight UTC. Live results will be available at the competition page. For added geek appeal, most of the contenders are available under open source licenses, so if you are weak in logic you can hack up your own brain extension and run it on an iPhone."
