Hi Rafael,
Having in mind the sort of operations such games have to make on boards, I ask: what are the best representations for a board in Haskell?
What works pretty nicely is using a one dimensional Data.Vector[1] to represent your board, a tuple (x, y) to represent a position on the board and then using a lens[2] to transform the tuple (x, y) into an index of the one dimensional Data.Vector. You can then write code like: -- get board value at position (1, 2) board ^. atCoord (1, 2) -- set board value at position (1, 2) board & atCoord (1, 2) .~ newValue Having a one dimensional vector has the advantage, that's a lot nicer to e.g. map or fold over it. In the toy example hsbot[3] I used this kind of representation.
