Optimal. Found by my solver. It is actually possible to feed this into some sokoban solvers and optimizers available on the Internet, but by the nature of these optimizers, there is no guarantee that the outputs of these optimizers are optimal. In fact, using different starting solutions, the same optimizer output different "optimized" solutions with different length. One of these "optimized" solution has length 139, which turns out to be suboptimal. Another of these solutions does have length 135, so sometimes these optimizers do give optimal solution, but you never know whether it is actually optimal with these optimizers. (But they are of great use since they run faster than an optimal solver, which can run out of resource quickly. In fact, this speedrun is found by disk-based bidirectional search.)
