AlphaDev is an artificial intelligence (AI) system developed by Google that uses reinforcement learning to discover enhanced computer science algorithms. It uncovered a faster algorithm for sorting, a method for ordering data. The algorithms generated by AlphaDev can transform how we program computers and impact all aspects of our increasingly digital society. The system is based on AlphaZero, a reinforcement learning model that defeated world champions in games like Go, chess, and shogi. AlphaDev is a significant stepping stone for using AI to optimize the world's code, one algorithm at a time.
