Nice speedrun I solved this with brute force in the editor years ago. I never rated not sure why.
Ive never understood how to solve any level with a pc or program.
Thanks for info below solved my first sokoban level earlier,was having a problem with 3 of the handemade ones.
Not tried Daves Reassembly maybe oneday.
Ps only 98 levels left to go, thanks again for soko solver sure this will help with quite a few more when I get the hang of it.

Added speedrun: 164 moves (old: 199).
Found with the help of computer. I first have my computer randomly generate one million positions inside the 6x6 square, filter out those positions which do not need to a solution, then used a crude heuristic to estimate the length of the sokoban part for each of the remaining positions. Then I chose a few of those with a small estimated length of solution, and used a variant of the vicinity search to shorten hard-coded silly solutions for those positions, and this solution is the result.

The details of vicinity search can be found at the sokoban wiki at <sokobano.de/wiki/> (look for the section "Optimizer development" -> "YASO Optimizer"). My variant is essentially the same as the setting infinity/0.

Added speedrun: 203 moves (old: 222).
Found by computer. Took only a few seconds of runtime. Probably not optimal, as my program terminates once it finds a solution.

A bit different placement this time. I haven't compiled an exhaustive list, but variations of the original placement account for at least 216 possible solutions, which brings the solution density up on the order of 2^-60. Still not attractive brute-force odds, but it's progress.
