pynpuzzle is an application that helps you to solve n-puzzle problem and also to test your algorithms for n-puzzle problem. It is written in Python and uses tkinter for it's graphical interface.
Open terminal and install these packages:
sudo apt-get install python3.5 python3-tk python3-psutilNow you can run pynpuzzle from terminal: ./pynpuzzle
Download and install Python's installer (version 3.5 or higher) from it's official website. After
installing python, open command line and install psutil package using pip: pip install psutil. Now you can run
pynpuzzle.py from command line: python pynpuzzle.py.
pynpuzzle loads algorithms from algorithms folder next to pynpuzzle.py.
All python files (.py) inside this folder (./algorithms/*.py) are considered as algorithms and pynpuzzle tries to load them.
An algorithm module should have a search function that accepts two arguments.
First argument is the n-puzzle's current state and the second one is the goal state.
Each of the arguments are two dimensional lists that represnt a n-puzzle.
For example (test_algorithm.py):
def search(state, goal_state):
"""
Test algorithm
"""
pass
Docstring of the function will be presented as the name of the algorithm in app's algorithms combobox (if function has no docstring, module's filename will be used. test_algorithm in this case.).
And finally, function should return an m*n*n three dimensional list which represents a set of paths from state to goal_state.
Logs about algorithm's modules can be seen from menubar's Show logs item.
These algorithms are included in the app and can be used as code examples for adding new and more complex algorithms:
