This is my first approach in CodinGame multiplayer challange. Read more about Coders Of The Caribbean contest.
I made two different approaches. First one is based on differen heuristics, you can find it before "feature" branch. Second one is based on estimator, it was developed in "feature" branch.
CodinGame, thank you a lot for a lot of fun I got during this contest, it was my first, hope not the last!
