The file is complete and valid. Here's what it does: **Maze Generation (Recursive Backtracker):** - Uses an iterative stack-based approach (no recursion limit issues) - 41×41 grid of cells with walls - Randomly chooses unvisited neighbors, carves passages, backtracks when stuck - Generates a perfect maze (exactly one path between any two cells) **Solvers:** - **A* Search**: Uses Manhattan distance heuristic, prioritizes cells with lowest f-score (g + h) - **BFS**: Explores level-by-level, guarantees shortest path in unweighted grid **Animation:** - Visited cells glow blue as the algorithm explores - Final path animates from green (start) to yellow (end) with glow effect - Speed slider controls how many cells are processed per frame **UI:** - "New Maze" generates a fresh random maze - "Solve" runs the selected algorithm with animated visualization - Legend shows color coding for start/end/visited/path The file is fully self-contained — no external dependencies, runs in any browser.
TAKE IT TO CODE
A single self-contained HTML file — copy it and open in any browser, or reuse the prompt with your own pi-agent run.
RUN
EVALUATION
Maze generates and renders well, but solver never triggers since only button clicks (not tested) start it; no keyboard/mouse response shown.

MEASUREMENTS
Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
