If you discover a nice starting configuration, I'll be happy to incorporate it into the applet with due references. When it's checked, you either set or remove pegs from the board. You may try creating your own starting configuration by selecting Design your own. You are able to retract as many moves as you made in a single game. Do not be afraid to experiment during the play: you can always backtrack by pressing the Undo button. (In the applet, there is a normally disabled checkbox Center to indicate the goal.) Configurations are selected from a combobox at the lower right corner of the applet. In others, to end up with a single peg at the center of the board. In some, the goal is to reverse the starting configuration. Other starting configurations are available. Therefore, the goal for this configuration is to end up with a single peg in the middle of the board. At the beginning, you are presented with the standard configuration where just one peg - the central one - is missing. The goal of a regular game is to reverse a starting configuration: Positions with pegs must become empty while empty positions should be filled with pegs by the end of the game. Then you click at the square (hole) to which you want the peg moved. To move a peg, you select it first by clicking on it once. The peg that has been jumped over is removed. Pegs (red circles in this implementation) are allowed to jump over adjacent (vertically or horizontally) pegs. This will be updated every time I drill deeper into a solution.Peg Solitaire (also known as Hi-Q) has very simple rules. SolutionCount = 0 - I want to keep track of the number of moves I have made in total. This list of all the moves to reach a solution I will store in a list called storeBoards. If I reach a dead end, I will delete the move that took me there. This means that when I find a solution I have a list of all the moves I made to get there.

StoreBoards = - I want to keep track of the moves I have made en route to a solution. This allows me to store the co-ordinates of each hole on the board alongside the information explaining if there is a peg or not at that location.

This would be an ideal puzzle to solve using Python.įirst of all I am going to show you my program in its entirety, and then take you through the programming of it line by line.įrom _future_ import print_function #Allows python3 use of print() import copy import datetime #Global Constants WIDTH = 7 HEIGHT = 7 CORNERSIZE = 2 #Global Variables gameBoard = - I am going to store my board in a dictionary. It's one of those things I have played with every so often, but never really tried to work out. My son started to play with Pin Solitaire at a friends house one day, and I gave him a hand explaining the game. More for my knowledge than anything else.

It turned out just learning how to actually do the Rubiks cube is much easier than you think! However, in the process, I had learnt a little about Breadth-first search and Depth-first search, and thought it would be great to solve a problem using one of these methods. It turns out the god number is 20.Īt this point I put the Python solution for the Rubiks cube aside, at least temporarily. This is the minimum number of moves needed to solve a Rubiks cube from any position. Finally I realised Google had thrown their weight behind the puzzle, and determined the 'god' number. and then I started to research how difficult a task it really was. I, naively, thought it would be a simple matter to churn through all the available options until the program stumbled across the solution. One of my earlier forays into solving a puzzle using Python was to solve the Rubiks cube. There is something hugely satisfying about finding the solution to a puzzle. I am a huge fan of puzzles, and think that my love of programming comes from that enjoyment.
