Sokoban AI Solver

Play Sokoban in your browser and watch an AI solver crack it. A plain-JS port of a native C++ engine, it returns the provably optimal (fewest-move) solution, entirely client-side.

In plain words

Sokoban AI Solver is a browser-based implementation of the classic 1980s puzzle game where players push boxes onto goals. It features an AI solver that finds the provably optimal solution with the fewest moves, running entirely in the browser through a JavaScript port of a C++ engine. Players can solve puzzles manually or watch the AI demonstrate the optimal solution path.

From the sources

Sokoban ("warehouse keeper") is a 1980s puzzle: push every box onto a goal. In this variant the keeper must also finish on a goal. The warehouse is a grid. On each step the keeper moves one square up, down, left or right. The keeper cannot walk into a wall or a box. It can push a single box if the square just beyond the box (in the push direction) is empty floor or a goal. Only one box moves per step, and a box can be pushed out of a goal again to make room. Sokoban is an A* search problem, but a naive version that explores one keeper step at a time explodes on crowded boards. What runs here is a plain-JavaScript port of a native C++ optimal solver I wrote. It returns the provably…from mkornreich.me

    A modern C++20 AI SDK (GPT‑4o, Claude 3.5, tool‑calling)2025 · ▲56

    Hi all, I’m hacking on new features for the ClickHouse native client and wanted the same “just call the model” ergonomics JavaScript and Python now enjoy. It didn’t exist for modern C++, so I wrote one. ai‑sdk‑cpp (Apache‑2.0) gives you: - Unified calls to OpenAI (GPT‑4o) and Anthropic (Claude 3.5) with a single C++20 API. - Streaming, multi‑turn chat, error handling—all std::optional/std::variant, no macros. - Tool calling (function‑calling) so the model can hit real APIs; sync or async, runs in parallel. The tricky bit: C++ still lacks real reflection, so mapping plain functions →…

  • Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  • Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
