![]() This section includes Join, Filter, and Union tools – which each play their part in confirming that the solutions generated by the algorithm are correct. I cross-reference the solutions against a list of known solutions that have been published online. Once the macro has generated solutions for all 1,000 puzzles, I want to ensure that these solutions are correct. I will dive deeper into this section in a few moments. This macro is where I keep the “secret sauce” – the algorithm that actually solves Sudoku puzzles. The “macro” is actually an entire workflow hidden inside one tool. This includes an Input tool that reads a CSV file containing 1,000 randomly selected Sudoku puzzles and a Select tool that allows me to clean my data before using it in the rest of the workflow. This workflow has four main parts, each consisting of multiple tools: A software tool that I enjoy using – Alteryx – is really useful for automating “analytic processes” such as this.īut wait! How can a Sudoku puzzle be solved with an “ analytic process ”? So, I decided to make a robot that can follow the same thought process that I was using but hopefully solve the puzzles a lot faster and without manual effort. My brain was having fun, but my writing hand was getting sore. This tedious manual effort can cause an infraction to Rule 3: “Have fun!”Īfter playing Sudoku many times myself, I realized that I was using the same patterns, again and again, to find the solutions to these puzzles. ![]() Sometimes, these strategies can be very repetitive and require a lot of manual effort to execute (the game is typically played on paper with a pencil). While the game itself can be challenging and complex, several strategies can be used successfully to find the solution. For very hard puzzles, that number can be much higher.
