Avoidable rectangle is applied (because other techniques are not implemented yet)
For now, it points out a flaw with my implementation of avoidable rectangle.
G4
should not be changed because G7
cannot be 6 and D7
cannot be 3. This means a double solution involving G4
is not possible, so the avoidable rectangle should not try to avoid it.
The technique needs to check if it would be a double solution if the three cells were swapped.
Just curious as to how you compiled the program. I've tried in Visual Studio 2017 and 2019 and it errored-out trying to open MainWindow.cs and SudokuBoard.cs. I'm an intermediate-level programmer trying to review the code to learn new techniques.
Hi!
What is the license for this project? I was looking to perhaps use some of your code in a project of my own, but there is no license specified.
Thanks in advance!
Hi, a very nice solver.
Interesting because it applies those strategies.
Visually appealing because it displays them and also shows what's going on in the grid.
But unfortunately it got stuck on a specific puzzle file I tested. I had tried that on paper and wanted to see a possible result by running it through your application. It got stuck after maybe 20 steps, reporting 'unsolved'. I don't know if it is a particularly hard puzzle.
I noticed there are a number of unsolved puzzles in one of your directories too.
So I wondered what the status is. Might there be some bugs, or is it a matter of working out more of those strategies?
I am particularly interested because I might work out my own version of this.
