Rubik's Cube Solver

Solver for a 3x3x3 Rubik's Cube implementing an A* algorithm with the Manhattan Distance as heuristics.

Code for the cube adopted from Miguel Hernando: https://github.com/mhernando/pyRubikSim

- Miguel Granero Ramos. 2021

Requirements:

As well as in Miguel Hernando's library:

pip install numpy
pip install matplotlib

or simply execute:

pip install -r requirements.txt

How to use:

The solver is wrapped around a Astar class. It need the cube to solve as parameter when instatiating. Example code can be found inside rb_solver.py.

# Create a cube
cube = rb.RubCube(3)

# Random movements
m=getRandomMoves(6)
print("Initial movements")
for x in m:
    print(x)
    cube.rotate_90(x[0],x[1],x[2])
print("Close the figure to start!!")
cube.plot()

solver = Astar(cube=cube, verbose=False)
movements = solver.solve()

print("Necessary moves {}: ".format(len(movements)))
for i in movements:
    print(i.movement)
    cube.rotate_90(i.movement[0],i.movement[1],i.movement[2])
cube.plot()
