Most of these were originally founded under the auspices of UNESCO. Of these, the discipline most closely related to Informatics is mathematics, and in fact in several count...
متن کاملSnapshots of the '99 Canadian Imo Team
I'm sitting at a table in a Frankfurt airport waiting room, playing bridge with three high school students. Slung about my waist is a fanny pack stu ed with passports and plane tickets for eight.

متن کاملA Generalization of an Imo Problem
Bill Sands has conjectured that for no integer n ≥ 3 does there exist a vector of n integers whose dot products with all permutations of (1, . . . , n) form a complete residue system mod n!. In this paper we verify this conjecture when n + 1 is not prime, n = 4, and n = 6. We also suggest a generalization of the problem.
