Uncovering Superior Algorithms:

AlphaDev employs advanced reinforcement learning techniques to generate algorithms that surpass those developed by scientists and engineers over several decades. One notable achievement is the discovery of a faster sorting algorithm—a fundamental process used by billions of people daily, often without their awareness. Sorting algorithms are the backbone of various applications, from search result rankings to data organization on computers and phones.

Open Source Adoption:

To ensure widespread adoption, AlphaDev has open-sourced these new sorting algorithms in the main C++ library. This move allows developers and companies worldwide to harness the power of these algorithms in their AI applications across industries such as cloud computing, online shopping, and supply chain management. This update marks a significant advancement, as it is the first time an algorithm designed through reinforcement learning has been added to the sorting library in over a decade.

The Evolution of Sorting:

Sorting has a rich history, with early examples dating back to the Great Library of Alexandria, where scholars alphabetized books manually. Over time, sorting machines and modern algorithms emerged, shaping the field of computer science. These highly efficient algorithms have been the result of extensive research and serve as foundational knowledge in the discipline.

A Unique Approach:

AlphaDev takes a unique approach to algorithm development by focusing on the lower level of assembly instructions, exploring opportunities for optimization that are harder to discover in higher-level coding languages. By delving deep into the computer’s assembly instructions, AlphaDev unlocks greater flexibility in storage and operations, offering significant opportunities to enhance speed and energy usage.

The Assembly Game:

Drawing inspiration from the success of AlphaZero, which defeated world champions in complex games like Go, chess, and shogi, AlphaDev trains by transforming sorting into a single-player “assembly game.” In this game, AlphaDev observes the algorithm it generates and the information within the CPU at each turn, selecting an instruction to add to the algorithm. This presents a significant challenge, as AlphaDev must explore countless instruction combinations to find an algorithm that not only sorts correctly but also outperforms existing ones.

Ensuring Accuracy and Efficiency:

Throughout the algorithm-building process, AlphaDev rigorously verifies correctness by comparing the algorithm’s output with the expected results. This ensures that the generated algorithm is not only faster but also accurate, providing a reliable solution for developers and users.


AlphaDev represents a major leap forward in algorithm development, harnessing the power of artificial intelligence to uncover superior solutions. By leveraging reinforcement learning and delving into the lower level of assembly instructions, AlphaDev has reshaped the landscape of code optimization. With the open-sourcing of its new sorting algorithms, developers and companies worldwide can now integrate these advancements into their AI applications, revolutionizing industries and paving the way for a more efficient and sustainable digital society. As AlphaDev continues to explore and enhance other areas of computer science, we eagerly anticipate the future breakthroughs it will bring.
