Method of successive substitution Method of successive substitution In modular arithmetic, the method of successive substitution is a method of solving problems of simultaneous congruences by using the definition of the congruence equation. It is commonly applied in cases where the conditions of the Chinese remainder theorem are not satisfied. There is also an unrelated numerical-analysis method of successive substitution, a randomized algorithm used for root finding, an application of fixed-point iteration. The method of successive substitution is also known as back substitution. Consider the simple set of simultaneous congruences Now, for "x" ≡ 3 (mod 4) to be true, "x" = 3 +
Computer Olympiad Starting in 1999, that event is now co-sponsored by the World Bridge Federation. Chess is a two-player board game played on a checkered game-board with 64 squares arranged in an eight-by-eight grid. Each player begins with 16 pieces of varying characteristics, the objective being to capture one's opponent's king piece. Many computer-versus-computer events are held beyond those of the Computer Olympiad. Chinese chess, is a strategy board game for two players from the same family as western or international chess. Known primarily as Xiangqi internationally, the game is referred to as Chinese Chess in the Computer Olympiad competitions. Chinese Dark
