Welcome to Al Zimmermann's Programming Contests. You've entered an arena where demented computer programmers compete for glory and for some cool prizes.
I run one or two contests per year. Each contest asks that you come up with your best solutions to a set of related computationally intensive problems. Although I speak of "programming contests", technically you don't need to write a computer program to enter. You can enter whether you use a computer, manual calculations, or tea leaves to solve the problems. You send me solutions, not programs.
To enter a contest, you need to Register. Once registered, you log on and submit your solutions through this website. You get instant feedback and your name immediately appears on the contest's standings page where, if you've done well, you can start to bask in some of that aforementioned glory.
