I often play games, when I have some free time. These games are often simple, but as a programmer, I often start thinking about it in terms of rules and how to solve it all. It's inspiration and need to relax a bit differently, that drives me to write these solvers. I will try to use only C++11, so they should be compilable under different OS, but I use linux and g++, so you probably need to create a new project from source under Windows (Visual Studio).
Simple solver for sudoku game. If I get back to it again, I'll try different method and maybe compare them in terms of speed. Method: Backtracking
Solver for a game, where goal is to fit a set of blocks into a space. Game space is in format of uniform integer grid. Method: Backtracking/Space Search
Program is a bit older, I'm not entirely sure about the input file or intended usage.
