Method Detail

isFeasible

public static boolean isFeasible(ControlInterface ci,
                 Row row)

Checks if the guess is valide or makes no sense in context of previous guesses and results. A guess is good (feasible) if, compared to each row, it scores the same result as the compared row did to the secret code.
In other words:
A code c is eligible or feasible if it results in the same values for Xk and Yk for all guesses k that have been played up till that stage, if c was the secret code.
X is the number of exact matches. Y is the number of guesses which are the right color but in the wrong position.

Parameters:

row - The guess to be checked.

ci - The control interface of a game which you want to use to check if a guess is feasible.

Returns:

True if guess is good. Otherwise false.

compare

private static int[] compare(Row a,
            Row b)

Compare two Rows to another.

Parameters:

a - The guess Row.

b - The secret code Row.

Returns:

[0] is the number of black pegs, [1] is the number of white pegs.
