Gödel's connection to theoretical computer science is that he was the first to mention the "P versus NP" question, in a 1956 letter to John von Neumann in which Gödel asked whether a certain NP-complete problem could be solved in quadratic or linear time.STOC is the ACM Symposium on Theory of Computing, one of the main North American conferences in theoretical computer science, whereas ICALP is the International Colloquium on Automata, Languages and Programming, one of the main European conferences in the field.To be eligible for the prize, a paper must be published in a refereed journal within the last 14 (formerly 7) years.The EATCS President and the SIGACT Chair each appoint three members to the committee, to serve staggered three-year terms.The committee is chaired alternately by representatives of EATCS and SIGACT.
