The most difficult game in the world - th

The most difficult game in the world is considered to be the first. This name came to European languages ​​from Japan. Full name of the game in Japan sounds like "i-th". According to various sources, its age is between 2,500 and 4,000 years. According to Chinese legend, he invented the game in the semi-mythical emperor Yao XXIV century BC. e., wishing to develop the mind and mindfulness heir to the throne.

Surprisingly, for many centuries of rule have not changed. It's pretty simple. For the game board is used, which marked 19 lines horizontally and vertically, forming a 361 square (game point). Two players take turns stones filled with these items. For convenience, the stones are painted in a contrasting color, such as black and white. The essence of the game is to earn as many points. To do this, you can capture territory (its surrounding empty points stones) or destroy the opponent's stones. To capture the enemy stone, need to surround it from all sides. This is where the difficulty begins. Although the rules are quite simple, the second is much more complex and the more chess checkers.

361-cell playing field creates a huge number of options. For comparison: in chess after the fourth stroke occurs about 100 000 possible positions, the number of more than 16 billion. If chess machines have long since learned to beat the best grandmasters in the laurels of the winner for them they are not yet available. To this there are several reasons. Firstly, as mentioned above, the number of options in the game is so huge that even a simple mechanical sorting extremely difficult. Secondly, there are serious problems with the position estimate. In chess for a long time developed criteria for evaluating the position and determine the value of the figures, and in the second it's much more difficult. Even the professional players are arguing about the possibilities of this or that combination. Currently, the best program for the game in the second - it MoGoTitan. It runs on a supercomputer capacity of 15 teraflops, ie processing 15 trillion operations per second, and is played only at the level of a strong amateur.
