Constructor Detail

SimpleFuseki

public SimpleFuseki(GameId id,
                    ModuleName name)
             throws InternalErrorException

Create the SimpleFuseki object.

Parameters:

id - The id of the game.

name - The name of this module.

Throws:

InternalErrorException - Thrown if the operation fails for any reason.

Method Detail

setPoints

private static void setPoints()

Read in the shimari combinations from the data file and set the points HashMap.

addPoint

private static void addPoint(Point pt1,
                             Point pt2)

Add a pair of points into the points HashMap.

Parameters:

pt1 - The key

pt2 - The value, which is placed in an ArrayList.

generateMove

public void generateMove(Module[] modules)

Generate the move for this module. The side effect of calling this method is that an array of RatedMove objects is stored which is returned by the getMoves() method.

Specified by:

generateMove in class Module

Parameters:

modules - An array of modules which this module needs in order to perform its work. Those modules reflect the current state of the board but are copies of the actual modules, so this method is free to manipulate them.

getShimaris

private void getShimaris(Board board,
                         Set moves)

Find any moves which would make shimaris, and rate them.

Parameters:

board - The Board module.

moves - The new rated moves are added to this Set.

isEmpty

private boolean isEmpty(Board board,
                        int distance,
                        Point pt)

Determine if the specified corner is empty except for the single point.

Parameters:

board - The Board module.

distance - The number of rows and columns to check out from the corner.

pt - The single point that is allowed to contain a stone.

Returns:

true if the corner is empty except for the single stone, or false.

getRatedMove

private RatedMove getRatedMove(Point pt,
                               Board board)

Create a RatedMove object from a point.

Parameters:

pt - The point to be made into a rated move.

board - The Board module.

Returns:

A RatedMove object for the given point.

getSideExtensions

private void getSideExtensions(Board board,
                               Geometry geo,
                               Set moves)

Find good points along the side, and add the rated moves to the set.. A point is considered to be good if it is on the third line just below the star point, and has room for a two space extension in either direction.

Parameters:

board - The Board module.

geo - The Geometry module.

moves - The Set to which the rated moves are to be added.

getCornerMoves

private HashSet getCornerMoves(short moveNumber,
                               Color color,
                               Geometry geo)

Get rated moves for all moves in empty corners.

Parameters:

moveNumber - the number of the next move.

color - The color of the side to move next.

geo - The Geometry module.

Returns:

A HashSet containing RatedMoves objects representing corner moves.

addCornerMoves

private void addCornerMoves(short moveNumber,
                            Color color,
                            Point pt,
                            Set set)

Rate different corner moves in the empty corner. Note that this is a very simple algorithm. The 3 - 3, 3 - 4, 4 - 4, and 4 - 5 points all get the top rating.

Parameters:

moveNumber - The number of the next move.

color - The color of the next move.

pt - The corner point

set - The set to which is to be added the RatedMove objects.

getDebugInformation

public Debug[] getDebugInformation(DebugType[] types)

Return the debug information for this module.

Specified by:

getDebugInformation in class Module

Parameters:

types - Only return a subset of the debug types in this array.

Returns:

The debug information that this module supports.

getDebugTypes

public DebugType[] getDebugTypes()

Return the types of debug information that this module supports.

Specified by:

getDebugTypes in class Module

getMoves in class Module

Returns:

An array of RatedMove objects.

getRequiredModuleList

public ModuleType[] getRequiredModuleList()

makeMove

public void makeMove(Move move,
                     Module[] modules)

move - The move that was just made.

modules - The modules that this method needs to perform its job.

clone

public Object clone()

Clone the module.

Specified by:
