title: What are the most important algorithms?
body: <p>Christoph Koutschan has set up <a href="http://www.risc.jku.at/people/ckoutsch/stuff/e_algorithms.html" rel="nofollow noreferrer">an interesting survey</a> that tries to identify the most important algorithms "in the world". Since one of the criteria is that "the algorithm has to be widely used" I though that extending the survey to the huge group of users at Stack Overflow would be a natural thing to do.</p>
  
  <p>So, what do you think? Which algorithms deserve a place in the Algorithm Hall of Fame?</p>
