isolation.Board class

Constructor

Board.__init__(self, player_1, player_2, width=7, height=7)

Attributes

BLANK : 0 (constant)

NOT_MOVED : None (constant)

width : 7 (constant)

Board width

height : 7 (constant)

Board height

active_player : hashable

Reference to a hashable object registered as a player with the initiative to move on the current board

move_count : int

Public Methods

apply_move(self, move)

Modify the game object by moving the active player on the game board and disabling the vacated square (if any). The forecast_move method performs the same function, but returns a copy of the board, rather than modifying the state in-place.

copy(self)

Return a new Board object that is a copy of the current game state

forecast_move(self, move)

Equivalent to apply_move, but returns a copy of the board rather than modifying the state in-place.

get_blank_spaces(self)

Returns a list of tuples identifying the blank squares on the current board

get_legal_moves(self, player=None)

Returns a list of tuples identifying the legal moves for the specified player

get_opponent(self, player)

Returns the opponent of the specified player

get_player_location(self, player)

Returns a tuple (x, y) identifying the location of the specified player on the game board, or None of the player is a registered agent in the game but has not yet been placed on the board. Raises a RuntimeError if the specified player is not registered on the board.

hash(self)

Return a hash of the current state (public alias of hash method). The hashed state includes occupied cells, current player locations, and which player has initiative on the board. An equivalent hash function can be added to the isolation.Board class from the isolation project:

is_loser(self, player)

Returns True if the specified player has lost the game in the current state, and False otherwise

is_winner(self, player)

Returns True if the specified player has won the game in the current state, and False otherwise

move_is_legal(self, move)

Returns True if the active player can legally make the specified move and False otherwise

to_string(self, symbols=['1', '2'])

Return a string representation of the current board position

utility(self, player)

Returns a floating point value: +inf if the specified player has won the game, -inf if the specified player has lost the game, and 0 otherwise.
