This Python project is a puzzle solver for the popular japanese Nonograms. They are also known as Hanjie, Paint by Numbers, Picross, Griddlers and Pic-a-Pix. I recommend reading the corresponding Wikipedia article on Nonograms. It explains very well how to solve them by hand.
This program is superior to other nonogram solvers because it can solve way more nonograms. In perticular those, in which you have to make an assumption and prove or disprove it. No other nonogram solver to my knowledge can solve those.
There are plenty of examples in the example_files folder, hand-solved solutions and their transcriptions. Some of them are marked hard which cannot be solved with traditional methods.
It can currently solve any nonogram without assumptions. But that is not really useful, because you can solve those by hand. I don't know why but it can't solve nonograms with assumptions for the life of it.
$ git clone https://github.com/jonaheinke/nonogram_solver.git
$ pip install numpy
$ python nonogram_solver.py example_files/example2.csvYou should write the row and column numbers into a CSV file delimited by ",", ";" or "|".
First you write the column numbers.
It is followed by a seperator line which contains at least one character that is not a number, space, tab or allowed delimiter.
Last you write the row numbers.
You can leave unused cells out or empty or use spaces so the number clusters look more like a complete matrix.
If it is not clear by now, look at the examples in the example_files folder.
Call the program with the path to the CSV file described under Commandline Usage.
