Functions

func Erase

func Erase(b *dragontoothmg.Board)

func Get

func Get(b *dragontoothmg.Board) (found bool, move dragontoothmg.Move,
	eval int16, depth int8, ntype uint8)

func Initialize

func Initialize(sizeInMb int)

Initialize (or reinitialize and clear) the table. Must be called before use.

func Load

func Load() float32

func Put

func Put(b *dragontoothmg.Board, m dragontoothmg.Move, eval int16, depth int8, ntype uint8)

Insert an entry into the transposition table, which requires the board position, the best move, the evaluation score, the entry search depth, and the node type.
