AlphaCode is a DeepMind system from 2022 that writes computer programs to solve competitive programming problems.
In plain words
Competition problems need you to understand a written puzzle and invent an algorithm, which was very hard for AI. AlphaCode used large transformer models to generate a huge number of candidate programs, then filtered them by how they behaved on examples, and submitted only a few. In simulated contests on Codeforces it ranked on average in the top 54.3% of participants.
A quick example
Imagine a contest puzzle about rearranging letters in a word. AlphaCode writes a very large number of candidate programs, runs them on the example tests, throws out those that fail, and submits only a few.
