From the README

**Watch DFS, BFS, UCS, A\* and greedy search think, one node at a time.**

Our SE3062 Intelligent Systems search code, running live in your browser 🧠✨

Breadth-first search on mediumMaze: cyan cells were explored first, pink ones last. Then Pac-Man walks the 68-step shortest path. 🟡

💡 Nothing is reimplemented in JavaScript. The page loads our actual search.py and searchAgents.py into Pyodide (Python compiled to WebAssembly), so the numbers you see are the same ones the autograder checks.

DFS expands the fewest nodes here, but it wanders: its path is almost twice as long.
