This article plus the fact that I have written a very detailed README and the entire codebase is well commented, so you should not have any problem understanding the code. It was #1 on Github Trending on a day in early February 2020. This project gained quite some traction on Github and it has garnered more than 750 stars so far! Another fun fact about this project is that it was #1 on Github Trending on a day in early February 2020. So if you are wondering about dabbling with it and possibly improving it, feel free to do it. This project is hosted on my Github at neeru1207/AI_Sudoku. I just wanted to illustrate the overall logic and flow of the application.

I didn’t go deep into every step and didn’t paste code snippets as it would be too long and boring if I did. “So around 70 hours of effort and the funny thing is that the GUI took more time than the AI part.” So around 70 hours of effort and the funny thing is that the GUI took more time than the AI part. All in all, this project was fun to work on but quite time-taking as well - It took me around ten days and 7 to 8 hours of effort each day to finish this project. from a Sudoku puzzle to an exact cover problem is done, we decided to focus on that subject in this thesis. Over 500 weekly posts give complete examples with move by move traces for you to follow, and detailed diagrams of. Diagrams and tables that aid solving are demonstrated.

The moment we hit a row or column without any white pixels at all, it means that we reached the end of the number! Systematic Sudoku (Sysudoku) is a human engineered way to solve Sudoku puzzles, and provides graphic and completely documented examples and collection reviews at all levels.

Start from the center of the image and start moving in all 4 directions.

So I found the bounding box of the number and centered the image by cyclically shifting the pixels. Since it ( mostly) worked, I decided to stick with it. I finally came up with the ( not so) brilliant solution of:įlood filling from the last 2 or 3 layers instead of only the outer layer. *Scratching head as frustration intensifies* If the white patches start somewhere from an inner layer, then we have a problem. If we flood fill from all the white outer layer points with black, then we can get rid of those ugly white patches ! They also add logic variety and increase the mental stimulation. According to Dave Green, president of Conceptis, many solvers find that Sudoku variants are more interesting, challenging and fun to solve. We need to get rid of those dirty white patches in the background but how? Sudoku is a universal and flexible concept, which enables the creation of many types of variants.
