Have you heard of TopCoder ( http://www.topcoder.com/tc http://www.topcoder.com/tc ) ? They run several algorithm competitions like this every month.

  Yeah. I've been practicing on topcoder and another, lesser known site, called codeforces.

    Codeforces is run by this dude [http://petr-mitrichev.blogspot.com/ http://petr-mitrichev.blogspot.com/] who is the #1 ranked algorithms programmer on TC. Pretty cool!
