checkDuplicate

public static java.lang.String checkDuplicate(ConstBoard board,
                              java.util.ArrayList<Compare.Placement> moves,
                              java.util.Map<java.lang.Integer,java.util.ArrayList<Compare.Placement>> games,
                              boolean useAlternate,
                              boolean isAlternated)

Check if game already exists in game collection. All games must have the same board size. Also finds rotated duplicates.

Parameters:

board - Board with the correct size (only used for Board.rotate).

moves - Moves of game to check.

games - Games in collection. The key is the game number, the value is the sequence of moves.

useAlternate - If true, assume that players are exchanged every second game. Only check games where player played the same color.

isAlternated - If useAlternate, indicate if game to check had players exchanged.

Returns:

String containing number of first identical game in collection or "-" if no duplicate was found. If a nearly identical game is found (<= 20% identical moves comparing moves by number), the game number is returned with a question mark appended.

                    throws java.lang.Exception
