Functions

func Choose

func Choose(s *State, player Player, depth int) (canMove bool, move position, desirability float64)

Choose returns the best move *for this player*, the desirability of the outcome *for this player*, and whether a move *by this player* is possible at all. The desirability is computed even if this player can't move

func Desirability

func Desirability(s *State, player Player) float64

func Eval

func Eval(s *State) (green float64, red float64)

Eval computes a "desirability" of a given state, for each player. This is not the same as the final score, where each cell counts for 1.
