Hello, thank you! This is part of project I done with other colleagues in university. Here's a sample Kakuro problem.
The first two values are width and height, the values are comma separated, empty fields (usually black in Kakuro representation) are 0/0, blank fields (the ones to be filled) -1/-1, constraint fields are in format HORIZONTAL_CONSTRAINT/VERTICAL_CONSTRAINT.
