A tungsten wire filament is placed inside a glass bulb, an electric current is passed through the filament, and resistance in the filament causes it to heat and âincandesceâ or glow. Most modern lamps feature a coiled filament that improves efficacy and reduces heat loss.
Indeed, the 277 move game was played in a tournament on the Internet Chess Club. Oddly enough, I found that the average length of a game (played by humans) is roughly 40 moves. Based on the statistics provided by the Chessgames database (685,801) games, the average number of moves is 40.04.
From there the number of permutations increases dramatically. Information theorist Claude Shannon estimated the total number of positions at 10^43, and with there being an average of 35 moves for each side per position, this makes the game tree in the order of 10^123. This is only positions, though. Since completely different potential move orders can create the same position, this makes the number of iterations much higher. After 1 (2 ply) move by each side, the number is 400 possible move combinations (20 * 20 400). After just 4 moves(8 ply), the number is over 197,000.
