All Implemented Interfaces:

GKStrategist, NSObject

public class GKMinmaxStrategist
extends NSObject
implements GKStrategist

The Minmax Strategist is a generic AI that selects a game model update for a given player that maximises potential gain, while minimising potential loss. It does this by examining all of the updates available to the player in question, extrapolating the potential moves opposing players may take, projecting out maxLookAheadDepth number of turns. The selected update will result in the greatest potential gain, balanced against the potential gain of other players.

bestMoveForActivePlayer

public GKGameModelUpdate bestMoveForActivePlayer()

Specified by:

bestMoveForActivePlayer in interface GKStrategist

bestMoveForPlayer

public GKGameModelUpdate bestMoveForPlayer(GKGameModelPlayer player)

Selects the best move for the specified player. If randomSource is not nil, it will randomly select which move to use if there are one or more ties for the best. Returns nil if the player is invalid, the player is not a part of the game model, or the player has no valid moves available.

gameModel

public GKGameModel gameModel()

Description copied from interface: GKStrategist

The game model that we wish to select updates for.

Specified by:

gameModel in interface GKStrategist

init

public GKMinmaxStrategist init()

Overrides:

init in class NSObject

maxLookAheadDepth

public long maxLookAheadDepth()

The maximum number of future turns that will be processed when searching for a move.

randomMoveForPlayerFromNumberOfBestMoves

public GKGameModelUpdate randomMoveForPlayerFromNumberOfBestMoves(GKGameModelPlayer player,
                                                                  long numMovesToConsider)

Selects one move from the set of N best moves for the specified player, where N is equal to numMovesToConsider. If randomSource is nil, it will not randomly select, but will behave like bestMoveForPlayer and return the first best move. Returns nil if the player is invalid, the player is not a part of the game model, or the player has no valid moves available.

randomSource

public GKRandom randomSource()

Description copied from interface: GKStrategist

A random source to use when breaking ties between equally-strong moves when calling bestMoveForPlayer or when selecting a random move when randomMoveForPlayer is called. If set to nil, bestMoveForPlayer and randomMoveForPlayer will simply return the first best move available.

Specified by:

randomSource in interface GKStrategist

setGameModel

public void setGameModel(GKGameModel value)

Description copied from interface: GKStrategist

The game model that we wish to select updates for.

Specified by:

setGameModel in interface GKStrategist

setMaxLookAheadDepth

public void setMaxLookAheadDepth(long value)

The maximum number of future turns that will be processed when searching for a move.

setRandomSource

public void setRandomSource(GKRandom value)

Description copied from interface: GKStrategist

A random source to use when breaking ties between equally-strong moves when calling bestMoveForPlayer or when selecting a random move when randomMoveForPlayer is called. If set to nil, bestMoveForPlayer and randomMoveForPlayer will simply return the first best move available.

Specified by:

setRandomSource in interface GKStrategist
