public class SimpleBigPoint

extends Module

implements BigPoint

This module generates bigpoints. These are points of high value in gote. For now this module only returns the hoshi points in the getBigpoints() method. The getMoves() returns an additional set of possible moves with a rating. These moves are near the hoshi an can be as valueable as the hoshi themselves or slightly less.

Constructor Detail

SimpleBigPoint

public SimpleBigPoint(GameId id,
                      ModuleName name)
               throws InternalErrorException

Parameters:

id -

name -

Throws:

InternalErrorException

Method Detail

fillHoshiPointArray

private void fillHoshiPointArray()

Get the hoshi points by their coordinates and put them into the hoshi 'member-array'

generateMove

public void generateMove(Module[] modules)
                  throws InternalErrorException

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.

InternalErrorException

investigateHoshiPoints

private void investigateHoshiPoints(Board b)

Check all hoshi points to see if they are free still and if so add them to the set of BigPoints (bp), at the same time put the subHoshi that belongs to it in the set as well.

Parameters:

b - The actual board to check for empty points

toRatedMoveArray

private RatedMove[] toRatedMoveArray(ArrayList rated)

creates a RatedMove array from an ArrayList of ratedMoves.

Parameters:

rated -

Returns:

addRatedMovesForHoshi

private ArrayList addRatedMovesForHoshi(Board b,
                                        Point point)

Add moves near the hoshi point to the RatedMoves array. All corner points are created equally and have the same value as the hoshi. Points near the hoshi's on the side have a slightly higher value when on the 3rd line then on the 4th. The point right below the hoshi has the same value as the hoshi. Points near the centre hoshi are not rated. (dan-rated stuff)

Parameters:

point - the hoshi to consider

createRatedMove

private RatedMove createRatedMove(Point pt,
                                  Board board,
                                  float rating)

Create a RatedMove object from a point.

Parameters:

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

board - The Board module.

rating - rating for this move.

Returns:

A RatedMove object for the given point.

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

Returns:

The types of debug information that this module supports.

getMoves

public RatedMove[] getMoves()

Get the, by getMoves(), generated list of RatedMoves

Specified by:

getMoves in interface ModuleInterface

Specified by:

getMoves in class Module

Returns:

An array of RatedMove objects.

getRequiredModuleList

public ModuleType[] getRequiredModuleList()

Return the modules that this module requires to perform its task.

Specified by:

getRequiredModuleList in class Module

Returns:

An array of module types that the module requires.

makeMove

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

Update the internal data structures of this module with the new move. This module is stateless, so minimal work is done here.

Specified by:

makeMove in class Module

Parameters:

move - The move that was just made.

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

getBigPoints

public Set getBigPoints()

Description copied from interface: BigPoint

Get all of the big points on the board.

Specified by:

getBigPoints in interface BigPoint

Returns:

An array of Stone objects.

isEmpty

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

Determine if the specified area is empty.

Parameters:

board - The Board module.

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

pt - The centre of the area to check.

Returns:

true if the area is empty or false.

isBigPoint

public boolean isBigPoint(Stone st)

Description copied from interface: BigPoint

Determine if the stone would occupy a big point.

Specified by:

isBigPoint in interface BigPoint

Parameters:

st - A Stone object.
