Nxnxn Rubik 39scube Algorithm Github Python Verified ✦ Free Access

A verified Python implementation typically involves defining the cube state as a string or an array of facelets.

Example Usage (from hkociemba/Kociemba):

import kociemba
# Define the cube state as a string
# Order: U1-U9, R1-R9, F1-F9, D1-D9, L1-L9, B1-B9
# Colors: U=White, R=Red, F=Green, D=Yellow, L=Orange, B=Blue
cube_state = 'DRLUUBFBRBLURRLRUBLRDDFDLFUFUFFDBRDUBRUFLLFDDBFLUBLRBD'
# Solve
solve_sequence = kociemba.solve(cube_state)
print(solve_sequence)
# Output example: "R2 U' B2 U2 L2 F' R2 U2 R2 D' L2 D' B' R' U2 F' L' F D' F2"

To implement a solver, you'll need to:

class RubiksCube:
    def __init__(self, size=3):
        self.size = size
        self.cube = [[[None for _ in range(size)] for _ in range(size)] for _ in range(size)]
def rotate_face(self, face, direction):
        # Implement face rotation logic
        pass
def apply_algorithm(self, algorithm):
        # Apply a sequence of moves to the cube
        pass
def solve_cube(cube):
    # Implement solving logic here
    pass
# Example Usage:
cube = RubiksCube(5)  # Create a 5x5x5 cube
solve_cube(cube)     # Solve the cube
