def compare(s1: TicTacToe, s2: TicTacToe): Int

Method to determine the ordering of two States. It is based on the heuristic.

Method to determine the ordering of two States. It is based on the heuristic.

Value parameters

s1

first S.

s2

second S.

Attributes

Returns

<0 if s1 < s2, >0 if s1 > s2, else 0.

def construct(proto: (Board, TicTacToe)): TicTacToe

Method to construct an S from a proto-state:

Value parameters

def getStates(s: TicTacToe): Seq[TicTacToe]

Concrete method to get the possible states to follow the given state s. The resulting sequence is in no particular order.

Concrete method to get the possible states to follow the given state s. The resulting sequence is in no particular order.

Value parameters

def isFirstPlayerToMove(s: TicTacToe): Boolean

Returns true if it is the first player's turn to move from state s.

Returns true if it is the first player's turn to move from state s.

To be completely unambiguous: the first player is the one who makes the very first move of the game. isFirstPlayerToMove(s) returns true when it is that player's turn again — e.g., for a two-player game, when an even number of moves have been made (sequence 0, 2, 4, ...).

It returns false when it is the second (or any subsequent) player's turn — i.e., when an odd number of moves have been made (sequence 1, 3, 5, ...).

Example (TicTacToe): empty board (sequence=0) → true (X moves first) after X plays (sequence=1) → false (O moves next) after O plays (sequence=2) → true (X moves next)

For games with more than two players, override this method as needed.

Value parameters

s

the current state.

Attributes

Returns

true if the first player is to move, false otherwise.

def isGoal(s: TicTacToe): Option[Boolean]

Have we reached a result? And, if so, who won?

Have we reached a result? And, if so, who won?

Value parameters

s

a (current) state.

Attributes

Returns

an Option[Boolean]: if None then this state is not a goal state. If Some(b) then: if b is true, we got a definite result, and the winner is determined by examining s in more detail. If b is false, we got a partial result, and we should continue to seek a more definite result.
