A fast command-line tool for solving Queens puzzles

Hacker News

I've been hooked on Queens puzzles ( https://www.linkedin.com/games/queens/ ) for the last few months, and decided to try and build a solver for them. Rather than doing a traditional solution search, I tried to model it instead on how humans solve these puzzles, iteratively eliminating and confirming possible squares for Queens. And since this was a side-project, I decided to go overboard, and try and make it as fast as possible (avoiding HashMap/HashSet in favor of bit fields, for example).
