Hi,
I keep getting an error when installing the module with pip. The message says "No module named 'pip.req'" and the exit code is 1. I don't know what to do to install it.
Thanks

error :
Not all 12 edges exist exactly once

Given the input: "oooyybgwbborbbrrbrwryyrywwwooyggyggbgwwboryggbgowwoyrr", I used the CFOP method which took 106 moves to solve.

Here is the Solution:
F2, Y, L, F, U', F', L', U, F2, Y, F, R, U', R', F', U, U, F2, Y, F2, F2, Y, B, U, B', U', R, U, R', U', R, U2, R', Y, U2, B, U, B', U, U, U, U, R, U2, R', U, R, U', R', Y, B, U, B', U, F', U', F, U', F', U', F, Y, U, F', U2, F, U', R, U, R', Y, Y, L', B', L, U', R', U, R, L', B, L, U, Y, Y, Y, Y, U, Y, Y, Y, R2, Y', D', R, U', R, U, R', Y, D, R2, Y, R, U', R'

The Kociemba algorithm for example only took 21 moves and the CFOP is supposed to take around 40 to 60 moves max. I don't really understand the program but I kinda get the concept of CFOP. Could someone explain what's going on? Thanks

I had 4 y moves in a row, three times, in my last scramble.

Scramble:
'YYYYYWYOYBBBBBBBBBRWRRRRRORGRGGGGGGGOROOOOOYOWYWWWWWGW'

Solution:
[U, F2, Y, F2, F2, Y, R', F', U, F, R, U, U, U, F2, Y, F2, F2, Y, B', U2, B, B', U', B, U, U, Y', R', U', R, U2, R', U', R, U, R', U', R, Y, Y, U2, U', R, U', R', U, R, U, R', Y, U', F', U, F, Y, R, U, R', U', U, F', U2, F, U', R, U, R', Y, Y, Y, R', U2, X, R', U, R, U', Y, R', U', R', U, R', F, Z', U, Y, Y, Y, Y, U, Y, Y, Y, Y, U, Y, Y, Y, Y, U, Y, R2, U, R, U, R', U', R', U', R', U, R']

The offending part has 'U y y y y U y y y y U y y y y U y' == 'U U U U y' == 'y'

Hello,

I am having difficulty understanding the notation used for the string input. From my interpretation of the documentation, the following code represents the mapping of colors to the faces of a cube:

color_side_mapping = { "red": "R", "white": "U", "orange": "L", "green": "F", "blue": "B", "yellow": "D" }

And this code represents the mapping of the faces to their respective indices in a string:

grid_size = 9
face_indices = dict()
face_indices['U'] = list(range(0, grid_size * 1))
face_indices['L'] = list(range(grid_size * 1 , grid_size * 2))
face_indices['F'] = list(range(grid_size * 2 , grid_size * 3))
face_indices['R'] = list(range(grid_size * 3 , grid_size * 4))
face_indices['B'] = list(range(grid_size * 4 , grid_size * 5))
face_indices['D'] = list(range(grid_size * 5 , grid_size * 6))

Example input: wwwwwwwwwooooooooogggggggggrrrrrrrrrbbbbbbbbbyyyyyyyyy

Any clarification would be greatly appreciated. Thank you.

Is there any way I could use the Cube class to generate a random cube?

Kociemba solver seems to need an specific position for the cube, it is:

• Front center cubie RED
• Top center cubie YELLOW
  Add a note in README or even in the code about this condition.

No acurate

when i want to import: from rubik_solver import utils

this error happened:

The solution that the cfop and beginners method solver outputs include a lot of "Y" rotations. I would like the use this for a solving robot that is unable to do full cube rotations. Is there any way to make the solutions not have rotations like the kociemba solution?
