The official site describes Lc0 as inspired by Google's Alpha Zero project, and the GitHub README describes the engine as the executable half of the LeelaChessZero project. ### Historique d'adoption The project became important beyond ordinary package installation because users could both run the engine and contribute self-play training games. The README says the training server enforces game quality using client and engine versions, and the official site separates downloading the engine from downloading a neural network. ### Modes d'utilisation Users typically run lc0 through a chess GUI or UCI-compatible interface, pairing the engine binary with a downloaded network. The README documents CPU and GPU backends including BLAS, CUDA, cuDNN, ONNX, Apple's Metal Performance Shaders, and experimental SYCL support. ### Pourquoi les passionnés de paquets s'y intéressent lc0 is a rare package-manager-facing chess engine whose useful artifact is not just code but a code-plus-weights ecosystem. It also represents a major open source response to AlphaZero: a reproducible, community-run neural-network chess engine distributed through source, binary releases, and operating-system package managers. ### Chronologie - 2018-05-30: GitHub lc0 repository created. - 2018-11-19: Official blog announced lc0 v0.19.0. - 2018-12-07: Official blog discussed AlphaZero paper details and lc0 v0.19.1. - 2019-05-28: Official blog announced that Lc0 won TCEC 15. - 2023-01-15: Official blog summarized 2022 progress, including contributors, search changes, network architecture changes, and new backends. - 2025-11-23: Release v0.32.1 published. ### Related projects - The official docs relate lc0 to AlphaZero, the LeelaChessZero training network, chess GUIs such as Nibbler, UCI-compatible chess tooling, TCEC competition, and backends such as CUDA, ONNX, BLAS, Metal, and SYCL. ### Sources - - - - - - - - ## Notes de sécurité broad file, network, media, or database tool signal. - **Risque Geiger:** blue / moyen - broad file, network, media, or database tool signal ## Détails de la base source - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** lc0 - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Autres enregistrements de gestionnaires de paquets - Nix - lc0: normalized package name match | nixpkgs package indexes: pkgs/by-name/lc/lc0/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 ## Liens liés - [Secret-risk packages](https://pkg.so/fr/secret-risk-packages/) - Has protected-tool coverage, approval-gate, or non-low Geiger security signals. - [Terminal utility packages](https://pkg.so/fr/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Networking and protocol packages](https://pkg.so/fr/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [Game and emulation packages](https://pkg.so/fr/game-emulation-tools/) - Matched game or emulation metadata. - [pkgconf](https://pkg.so/fr/brew/pkgconf/) - Build dependency declared by Homebrew. - [cmake](https://pkg.so/fr/brew/cmake/) - Build dependency declared by Homebrew. - [ninja](https://pkg.so/fr/brew/ninja/) - Build dependency declared by Homebrew. - [meson](https://pkg.so/fr/brew/meson/) - Build dependency declared by Homebrew. - [fairy-stockfish](https://pkg.so/fr/brew/fairy-stockfish/) - Shares pkgdb curated category or tags: chess, cli, engine, games, uci. - [fairymax](https://pkg.so/fr/brew/fairymax/) - Shares pkgdb curated category or tags: chess, cli, engine, games. - [polyglot](https://pkg.so/fr/brew/polyglot/) - Shares pkgdb curated category or tags: chess, cli, games, uci. - [stockfish](https://pkg.so/fr/brew/stockfish/) - Shares pkgdb curated category or tags: chess, chess-engine, cli, games, uci. - [cheops](https://pkg.so/fr/brew/cheops/) - Shares pkgdb curated category or tags: chess, cli, engine, games. - [fheroes2](https://pkg.so/fr/brew/fheroes2/) - Shares pkgdb curated category or tags: cli, engine, games. - [gnu-chess](https://pkg.so/fr/brew/gnu-chess/) - Shares pkgdb curated category or tags: chess, cli, games, uci. - [lgeneral](https://pkg.so/fr/brew/lgeneral/) - Shares pkgdb curated category or tags: cli, engine, games. ## Combined YAML source View the package source record on GitHub.
