getHighestScorePossible

public static int getHighestScorePossible(GameState state,
                                          CardColour colour)

Calculates the maximum possible score obtainable for the given colour

Parameters:

state - The game state

colour - The colour to look at

Returns:

The maximum possible score

isSafeToDiscardHigherThanPossible

public static boolean isSafeToDiscardHigherThanPossible(GameState state,
                                                        CardColour colour,
                                                        Integer value)

Returns true if the card is safe to discard because it is higher than what is currently possible for its colour

I.e if all the Blue 2's have been discarded and none played, then any Blue 3, 4 or 5 is safe to discard

Parameters:

state - The game state

colour - The colour of the card to consider

value - The value of the card to consider

Returns:

Can we safely discard it for this reason?

isSafeToDiscard

public static boolean isSafeToDiscard(GameState state,
                                      int player,
                                      int slot)

Returns true if a given card is safe to discard. Works on what the player has, not what they know

Parameters:

state - The game state

player - The player

slot - The slot

Returns:

Whether it is discardable
