Methods

GetAllLiberties(Board, int, int)

A function which finds all the liberties attached to a specific stone by flood filling the group until it reaches the edges.

public static HashSet<(int column, int row)> GetAllLiberties(this Board board, int col, int row)

Parameters

board Board

The board which is to be searched.

col int

The column of the space to be checked.

row int

The row of the space to be checked.

Returns

HashSet<(int x, int y)>

A HashSet<T> with each of the locations of the empty spaces surrounding the group.

Remarks

This method may be deprecated in the future, as the GetGroups(Board) method performs this same lookup for all groups on the board.

GetGroups(Board)

Finds all groups of stones on a given board. Does this in single access of each space on board for a constant time lookup.

public static IReadOnlyDictionary<SpaceState, HashSet<Group>> GetGroups(this Board board)

Parameters

board Board

The board which is to be searched.

Returns

IReadOnlyDictionary<SpaceState, HashSet<Group>>

A dictionary which maps each SpaceState to a HashSet<T> of Groups of spaces. Each "internal" hashset corresponds to one contiguous group of stones.

Remarks

Also returns all groups of empty stones, which could be very useful for estimating scoring.
