AlphaZero

AlphaZero is a type of artificial intelligence (AI) that can learn how to play a game without needing to be taught what moves to make. It does this by using an algorithm called something called a "reinforcement learning approach". Basically, AlphaZero plays against itself repeatedly and tries different strategies to see which one works best. It then remembers the strategies that work best and chooses those over the ones that didn't work so well. This allows AlphaZero to become really good at the game without anyone having to teach it.
