Introduction to Competitive Programming
chrisjrn writes "Last year, I unexpectedly found myself entered in the Australian Computer Programming Competition, and somehow did well in it. As a result I decided to write a guide as an introduction, for high school-level students (and others, I suppose,) into the world of programming competitively based on my experience, and how to go about successfully competing in competitions." Article looks like a good start, I'm sure Slashdot readers can add many more tidbits of wisdom.
- ACM International Collegiate Programming Contest: http://icpc.baylor.edu/icpc/ (Big competition between colleges worldwide - sort of the equivalent of the IOI at the university level).
- TopCoder: http://www.topcoder.com/tc (weekly matches, yearly competition with large cash prize, also hosts the Google Code Jam (http://google.com/codejam)).
