How AlphaDev Works: Learning (The Smart Way)
At the heart of AlphaDev is reinforcement learning. In this AI approach, agents learn by receiving rewards for correct actions in their environment. In AlphaDev's case, the environment involves assembly-level program execution. The agent constructs sequences of instructions to solve problems such as sorting lists as efficiently as possible.
AlphaDev uses a modified version of DeepMind's AlphaZero algorithm, playing a game of its own, discovering optimized instruction sequences instead of dominating board games. With an emphasis on spotting bottlenecks and finding paths with fewer operations, AlphaDev supplies improvements that even skilled engineers haven't detected yet.
