Generate a random maze with the recursive-backtracker algorithm on a canvas, then animate an A-star or BFS solver finding the path from start to finish.

I'll create a single-page web app that generates a random maze using the recursive backtracker algorithm and then animates an A* solver finding the path from start to finish.

I've created a single-page web app that generates a random maze using the recursive backtracker algorithm and animates an A* solver finding the path from start to finish. **Features:** - **Recursive backtracker maze generation** - creates perfect mazes (every cell reachable, no loops) - **A* pathfinding solver** with Manhattan distance heuristic - **Interactive controls**: Generate new maze, solve, reset - **Speed slider** to adjust animation speed - **Statistics**: cells visited, path length, solve time - **Color-coded visualization**: - Green: start cell - Red: end cell - Orange: visited cells during solving - Blue: final path - **Fully self-contained** - no external dependencies or network requests The app automatically generates a maze on load. You can adjust the speed slider to control the animation speed, then click "Solve with A*" to watch the algorithm find the path. The statistics update in real-time as the solver progresses. All code (HTML, CSS, JavaScript) is contained in a single `index.html` file.

EVALUATION

3/5 partial

Maze generates and regenerates but the A* solver never appears to visualize a solved path in any panel.

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.
