In our paper, published today in Nature, we introduce AlphaTensor, the first artificial intelligence (AI) system for discovering novel, efficient, and provably correct algorithms for fundamental tasks such as matrix multiplication. This sheds light on a 50-year-old open question in mathematics about finding the fastest way to multiply two matrices. This paper is a stepping stone in DeepMind’s mission to advance science and unlock the most fundamental problems using AI. Our system, AlphaTensor, builds upon AlphaZero, an agent that has shown superhuman performance on board games, like chess, Go and shogi, and this work shows the journey of AlphaZero from playing games to tackling unsolved mathematical problems for the first time.

More than two excruciatingly long years after the RTX 30-series reveal, a new generation of graphics cards is finally here. Nvidia CEO Jensen Huang unveiled the hotly anticipated GeForce RTX 4090 and not one, but two different RTX 4080 variants during the "Project Beyond" reveal event that kicked off GTC 2022. These graphics cards look absolutely monstrous, full stop, with the RTX 4090 leaving the RTX 3090 Ti stumbling in its wake. But while the performance of these next-gen GeForce GPUs promises to melt your face, the raw speeds are far from the only interesting aspect of this launch. Here are seven must-know facts from the RTX 4090 and RTX 4080 reveal, from ray tracing advancements to staggeringly high new sticker prices for Nvidia's GPUs. Nvidia clearly designed its new "Ada Lovelace" architecture to scream through ray tracing tasks.

Games potentially provide a wealth of knowledge about our shared cultural past and the development of human civilisation, but our understanding of early games is incomplete and often based on unreliable reconstructions. This paper describes the Digital Ludeme Project, a five-year research project currently underway that aims to address such issues using modern computational techniques.

Nvidia's GeForce RTX 3080 graphics card symbolizes why we tell people to wait for the second generation when bleeding-edge technology appears. The radical new-look Turing GPUs inside Nvidia's GeForce RTX 20-series packed all sorts of cutting-edge technologies designed to usher in real-time ray tracing, a long sought-after goal for the gaming industry. Not only did Turing introduce specialized RT cores devoted to processing ray tracing tasks, it also debuted tensor cores, dedicated hardware that uses machine learning to help denoise ray traced visuals and enable AI-enhanced tools like the fantastic Deep Learning Super Sampling (DLSS) technology. Turing's improvements also extended to the traditional shader cores, introducing an overhauled processing pipeline better equipped to handle games built using the newer DirectX 12 and Vulkan graphics APIs. All of these were huge departures from the norm.

Microsoft is to launch a radical'Netflix for games' service for $9.99 per month. The'Game Pass' service will offer 100 Xbox One and Backward Compatible Xbox 360 games to users. It will update its catalogue of games each month, and users will have the option to download games - although they must keep paying their subscription to play them.

It has revolutionised the way we watch TV shows and movies. But could a Netflix-style service have the same impact on the world of video gaming? One expert believes so and has argued that it could be vital to the future diversity of the industry. Traditionally vast amounts of money was spent on headline grabbing franchise games, as well as some smaller standalone titles, which would then be recuperated through sales. The focus was on engaging single-player story lines, akin to movies, with classics like Assassin's Creed, Resident Evil and Tomb Raider.

This short note proposes the study of ancient games as a new frontier for game AI research. This aspect of games research has been largely neglected so far from an AI perspective, but could benefit significantly from the application of modern computational techniques.
