Re:Show HN: Rubiks Cube Solver

Not in practice. Computing the absolute minimum solution for every possible position is computationally infeasible for a web-based solver. This uses Kociemba’s two-phase algorithm instead, which produces very efficient solutions, usually close to optimal, without requiring enormous amounts of time and memory.

Why infeasible? cube20.org says "a good desktop PC" can optimally solve 0.36 random positions per second. And that's from the year 2010. I don't see why a web-based solver 16 years later should be much slower.
And apparently vcube optimally solved six cubes per second eight years ago already: https://github.com/Voltara/vcube
