Maze Solver Benchmark — BFS Shortest Path by Maze Size
Search effort and path length for the LK Forge Maze Solver, which generates a perfect maze with a recursive-backtracker and finds the unique shortest path with breadth-first search. 200 seeded mazes per size.

Headline numbers (200 mazes each)
| Maze | Open cells | Mean shortest path | Mean cells visited by BFS | % of open cells explored |
|---|---|---|---|---|
| 12×12 | 287 | 131 | 185 | 64.5% |
| 20×20 | 799 | 308 | 487 | 60.9% |
| 30×30 | 1,799 | 607 | 1,071 | 59.5% |
| 40×40 | 3,199 | 972 | 1,784 | 55.8% |
In a perfect maze there is exactly one path between any two cells, so BFS returns the unique shortest route. It explores a fairly stable ~56–65% of all open cells before reaching the exit, and both path length and search effort scale roughly linearly with the number of open cells.
Files
data/maze-benchmark.json— per size: open cells, mean shortest-path length, mean cells visited, % explored.
Method
- Engine: the recursive-backtracker generator and BFS solver copied verbatim from the shipped
maze-solver.js(DOM stripped,Math.random→ seeded RNG, size parametrized). - Cells visited = BFS dequeue count (machine-independent search effort).
Reproduce
