A Sokoban solver program is a program that tries to solve Sokoban levels. There are several solver programs available. (See Sokoban solvers.)
Solver programs may have different objectives:
- Find any solution
- Find push optimal solutions
- Find push optimal solutions with best moves
- Find move optimal solutions
- Find move optimal solutions with best pushes
Given the computational complexity of these tasks, a solver program is usually designed for just finding any solution. If a solution is to be optimized, an optimizer program can be used. (See Optimizers.)
The statistics presented here provide a picture of what the best freely available Sokoban solvers can do.

General benchmarking information
For practical reasons, almost all tests have been performed with a 10 minutes time limit. The tests are, however, not a 10 minutes contest but a showcase for what the solvers can do, so other time limits are entirely feasible.
The hardware used for the tests is a standard PC with a modern operating system (64bit).
Tests are performed with default solver settings, except that RAM usage may be increased manually 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.

Open Test Suite
The statistics shows the results for the leading Sokoban solvers for various level collections. 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.
This test suite may be changed by adding new level collections from time to time.

GroupEffort Test Suite
The only reason for benchmarking the GroupEffort test suite is to demonstrate 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.
