This is a Rubik's cube solver that uses Kociemba's two-phase algorithm. However, please note that this is still a work in progress and the implementation is not yet efficient. The solver does not currently use symmetric reductions, pre-moves, or multi-threaded search.
By default, there is no timeout, which means the solver will return the first solution it finds. However, by adding a timeout, the solver will continue searching until the timeout has elapsed and return the shortest solution found or nothing. Specifying a lower search depth can result in better solution quality (around 21 to 23 moves), but it can also make the search slower if the depth is less than 20 moves. Nevertheless, it has been proven that all cases can be solved in 20 moves or fewer.
kewb help
kewb solve --scramble "R U R' U'" --max 22 --timeout 1 --details
kewb solve -s "R U R' U'" -m 22 -t 1 -d
# default values: max = 23, timeout = none, details = false
kewb scramble
kewb scramble -n 5
# default values: number = 1
# default values max: 23, timeout: none, details: falseNB: You must have the rust toolchain installed
