rubik-sim 1.0.0

Basic Rubik's cube (3x3) simulator

Rubik Sim

This project allows to simulate a 3x3 Rubik's cube and perform operations over it.

⚙️ Setup

Requirements

• Python 3.9 or higher

Installation

The package is installable via pip:

pip install rubik-sim

Alternatively, the 'develop' branch can be installed for the latest changes

pip install git+https://github.com/Jtachan/genetic_rubiks_solver.git@develop

🏃 Usage

Initializing the cube

The package allows importing all the classes directly from the module.

To initialize the cube, it is only needed the RubiksCube class. This generates a fully solved cube. To obtain a random state using scramble()

from rubik_sim import RubiksCube

my_cube = RubiksCube()  # Solved cube
my_cube.scramble()  # Updates the cube by 25 random moves

The number of moves to scramble the cube can also be specified as a parameter:
RubiksCube.scramble(nof_moves: int = 25)

It is also possible to initialize any cube from a string of characters defining the color of each tile.

my_cube = RubiksCube.from_color_code(
    'BBBBBBBBBGGGGGGGGGOOOOOOOOOYYYYYYYYYRRRRRRRRRWWWWWWWWW'
)

The only supported colors are green ('G'), orange ('O'), yellow ('Y'), red ('R'), white ('W') and blue ('B').

Representation

The cube's state can be represented by calling print()

>>> print(my_cube)
             ['B' 'B' 'B']
             ['B' 'B' 'B']
             ['B' 'B' 'B']
['G' 'G' 'G']['O' 'O' 'O']['Y' 'Y' 'Y']['R' 'R' 'R']
['G' 'G' 'G']['O' 'O' 'O']['Y' 'Y' 'Y']['R' 'R' 'R']
['G' 'G' 'G']['O' 'O' 'O']['Y' 'Y' 'Y']['R' 'R' 'R']
             ['W' 'W' 'W']
             ['W' 'W' 'W']
             ['W' 'W' 'W']

From the representation, the faces are:

• Blue = Top (up) face
• Green = Left face
• Orange = Front face
• Yellow = Right face
• Red = Back face
• White = Bottom (down) face

Rotating the cube

RubiksCube.perform_operations(operations: Sequence[NOTATION_MOVES])

This method updates the current state of the cube by performing operations over it. The supported operations are:

U, U', U2, D, D', D2, R, R', R2, L, L', L2, F, F', F2, B, B', B2, M, M', M2, E, E', E2, S, S' and S2.

These are the general notations for the possible moves on the cube. More about the Rubik's cube notation: https://ruwix.com/the-rubiks-cube/notation/

Any missing notation can be performed with the current notations.
