Now we can actually dig into solving the puzzle. First though is the internal representation of the puzzle. There are many ways to do this but I've elected to largely disregard that the puzzle takes place on a board and instead focus on where the ships are. That is, each ship can be in a large number of places. But it can only be in one place at a time and when it is in that place, other ships won't be able to occupy nearby or overlapping positions. To solve the puzzle, every one of these interactions will be recorded and any combinations that don't collide must be a solution. |
