> Memorization of algorithms. You don't need to memorize them. You can have some amount of printouts with you, which teams usually use for having a bugfree implementation of stuff like arbitrary graph matching, maximum matching of lowest cost, 2SAT or just Gauss elimination. At the same time these advanced algorithms do not get used very often -- in the 2 finals I took part in we've used something from out printouts maybe once.
