Introduction Prologue The very first thing I’ve worked on upon starting my PhD is Pseudorandom Quantum States, or PRS for short. In particular, I realized that in the proof of Brakerski and Shmueli, one inequality was unnecessarily loose, meaning that we could improve the bound on the trace distance. It was definitely not worth writing anything about it, and so I forgot about it. Some time late...

Coding the AlphaZero search algorithm from scratch - Part 2: Implementing the MCTS algorithm2024-08-15T15:50:00+02:00 2025-02-13T01:21:03+01:00 https://perso.telecom-paristech.fr/tnemoz/posts/coding-the-alphazero-search-algorithm-from-scratch-part-2/ Tristan Nemoz

Now that we’ve seen in the previous article how the MCTS algorithms works, let us implement it on an actual game: chess! The reasons why I chose this game are: I’m familiar with chess, and thus can understand what the frick the AI is doing; AlphaZero is supposed to work well when playing chess, so we’re supposed to see some improvements between the pure MCTS version and the improved AlphaZ...

One algorithm I’ve always been fascinated with is AlphaZero. I’ve wondered for quite some time how good it would be if I made it play other games. So, in order to figure it out, and to deepen my understanding of it, I decided to code it myself. This post is part of a series about AlphaZero. You can find the other posts here.
