Summarizing https://www.deepmind.com/blog/alphadev-discovers-faster-sorting-algorithms
Here's my try:
DeepMind's AlphaDev team discovered faster sorting algorithms by starting from scratch rather than refining existing algorithms. They began looking where most humans don't - the computer's assembly instructions. The team open-sourced their new sorting algorithms in the main C++ library, which are now used by millions of developers and companies across industries.
The assembly game is incredibly hard because AlphaDev has to efficiently search through an enormous number of possible combinations of instructions to find an algorithm that can sort, and is faster than the current best one. The number of possible combinations of instructions is similar to the number of particles in the universe or the number of possible combinations of moves in games of chess (10120 games) and Go (10700 games). And a single, wrong move can invalidate the entire algorithm.
As the algorithm is built, one instruction at a time, AlphaDev checks that it’s correct by comparing the algorithm’s output with the expected results. For sorting algorithms, this means unordered numbers go in and correctly sorted numbers come out. We reward AlphaDev for both sorting the numbers correctly and for how quickly and efficiently it does so.
The assembly game is incredibly challenging because it requires AlphaDev to think about the problem from first principles, without relying on existing code or knowledge of other algorithms. It also requires AlphaDev to be creative and innovative in finding new ways to solve the problem.
AlphaDev's approach has been successful because it allows us to explore a vast space of possible algorithms, many of which are much faster than previous methods. This has led to significant improvements in the performance of our machine learning models, as well as advances in other areas such as computer vision and natural language processing.
