our program AlphaGo achieved a 99.8% winning rate against other Go programs, and defeated the human European Go champion by 5 games to 0. This is the first time that a computer program has defeated a human professional player in the full-sized game of

AlphaGo Zero: Starting from scratch Following the summit, we revealed AlphaGo Zero. While AlphaGo learnt the game by playing thousands of matches with amateur and professional players, AlphaGo Zero learnt by playing against itself, starting from completely random play.

In contrast, the AlphaGo Zero program recently achieved superhuman performance in the game of Go, by tabula rasa reinforcement learning from games of self-play. In this paper, we generalise this approach into a single AlphaZero algorithm that can achieve

AlphaGo is a computer program that plays the board game Go.[1] It was developed by DeepMind Technologies [2] which was later acquired by Alphabet Inc.’s Google. AlphaGo had three far more powerful successors, called AlphaGo Master, AlphaGo Zero[3] and AlphaZero. In October 2015, the original AlphaGo became the first

History ·

AlphaGo Zero is a version of DeepMind’s Go software AlphaGo. AlphaGo’s team published an article in the journal Nature on 19 October 2017, introducing AlphaGo Zero, a version created without using data from human games, and stronger than any previous version. [1]
