Solver Statistics

From Sokoban Wiki

Revision as of 17:12, 28 November 2021

Sokoban solvers are programs that solve sokoban levels. There are many programs available that can solve Sokoban levels (see Sokoban solvers).

There are different types of solvers:

1. Solvers trying to find any solution
2. Solvers trying to find push optimal solutions
3. Solvers trying to find push optimal solutions with best moves
4. Solvers trying to find move optimal solutions
5. Solvers trying to find move optimal solutions with best pushes

Usually, a solver is designed to just find any solution. If the solution is to be optimized an optimizer program can be used (Optimizers).

To get an impression of what levels are solvable by which solver, here are some statistics.

General bench run information

All tests are performed with a 10 minutes time limit. For the famous XSokoban set an exception is made when a solver can solve all 90 levels with a higher time lmit.

The hardware used for performing the bench runs is a standard PC with a modern operating system (64bit).

The bench runs are performed with the default settings of the solvers. The RAM usage may be increased when this is beneficial.

XSokoban Test Suite

The XSokoban level set is the de facto standard test suite in the academic literature on Sokoban solver programming.

Large Test Suite

The large test suite comprises level packs selected for being a challenge for the solvers, but not too difficult. The statistics shows the results for the leading Sokoban solver programs.

This test suite is not subject to change, as it is meant to be a "Large Standard Test Suite" for Sokoban solver programs.

Solver Statistics

The statistics shows the results for the leading Sokoban solvers for various level packs. Please note that the grand totals are simple summations. The number of solved unique levels may differ slightly due to duplicate levels in the level packs.

GroupEffort Test Suite

The only reason for benchmarking the GroupEffort test suite is to show the limited veracity of the statement made in section "6 Conclusion" of the thesis, where the author writes that the GroupEffort solver "outperforms existing solvers".

The benchmarks show that this was only true for the cherry-picked small test set at the time the thesis was published, never for the presumably more representative large test set.

(a): Time limit: 5 minutes     (b): Time limit: 10 minutes     (c): Best GroupEffort solver configuration
