Today, the final fifth contest took place between the AlphaGo computer program developed by DeepMind (owned by Google) and the world’s strongest player in the world – champion Lee Sedol from South Korea. Note that in the first three games artificial intelligence won. In the fourth game, the man managed to take up over AlphaGo. Despite the winning time position, the Google AI made a mistake on move 79. Already at move 87, the program realized this, but Lee Sedol still managed to get out of the game as a winner. Regardless of the outcome of the fifth match, the final victory has already been ranked by AlphaGo, and Google will spend the prize million dollars on charity. So, AlphaGo artificial intelligence became the winner of the fifth game again. Despite the fact that during the four games Lee Sedol appreciated the features and behavior of the program, applying various tactics in the previous rounds, this did not help him at the final stage. As in the fourth game, the Korean tried not to give up the AlphaGo initiative, constantly attacking the already designated enemy territory. Until recently, the players were on an equal footing and, as commentators noted, a clear victory for a particular participant was not observed. After five hours of the game, Lee Sedoll admitted defeat by laying a white stone on the gobana – the opponent’s stone (AlphaGo played with white stones, a man with black stones). Based on the results of the games, the Game Association of the Republic of Korea assigned AlphaGo computer program the highest, ninth dan. As noted in the association, this is the first ever rewarding of a player with the highest dan. The corresponding certificate will be awarded today to the development team.
