Nxnxn Rubik 39scube Algorithm Github Python Patched

Algorithm:

r2 B2 U2 l U2 r' U2 r U2 F2 r F2 l' B2 r2

(r = right inner slice, l = left inner slice)

cube = RubikCubeNxN(4)

Steps:

Why Python? Python’s list comprehensions and NumPy (for N>10) make rotation and state manipulation intuitive, albeit slower than C++. nxnxn rubik 39scube algorithm github python patched

r2 U2 r2 u2 r2 u2

(u = upper inner slice)

These are patched into the solver’s final stage. Algorithm: r2 B2 U2 l U2 r' U2 r U2 F2 r F2 l' B2 r2

To confirm you are using a patched version:

grep -i "parity" /path/to/solver.py
# Should show parity fix comments.

# Patched rotation function
def rotate_face_numpy(cube_array, face_index):
    cube_array[face_index] = np.rot90(cube_array[face_index], k=-1)
    # ... update adjacent faces using numpy indexing

from array import array self.state = [array('b', [0]) * (N*N) for _ in range(6)] # flattens each face (r = right inner slice, l = left
