Sovle a rubik's cube using the A* algorithm.

Requirements

You can create a virtualenv and use pip install -r requirements.txt, but at the moment the only dependency is numpy.

class RubikCube methods

The internal representation of the rubik cube is a numpy.ndarray() with a (9, 12) shape.

• RubikCube.__init__(self) Create a new instance of a RubikCube()
• RubikCube.__str__(self) Return a string of the internal representation.

>>>

• RubikCube.scramble(self, moves=5000) Scramble the rubik cube.
• RubikCube.x_rotate(self, slot, direction) perform a single rotation on the x axis.

>>> rc.x_rotate('top', 'left')
>>> rc.x_rotate('bottom', 'right')
