At least I believe if he should try to avoid trivial nil operations, like reverse palindromic subsequences, and put the scramble sequence in a standard form, but as you said, just generating unbiased scramble is certainly not possible by just throwing a bunch a random moves.. | |
| Jan 12, 2016 at 10:22 | comment | added | theosza | Making a good cube scrambler is surprisingly hard. Might not matter when you just want to practise, but a competition-level scrambler should give an unbiased scramble (all cubes equally likely). The way to do this is generate a random (solvable) cube. Solve it using a near-optimal algorithm like Kociemba's algorithm. Then the scramble is the inverse of the solution moves. Neither the generating nor solving of the cube are trivial. | |

Slightly improved readability
