Constants

	ORIG_HASH_CAP       = 1 << 20
	MAX_PHASE           = pieces.MAX_PHASE
	MAX_PIECE_PHASE_SUM = 24

	PV_NODE  = uint8(0)

Variables

var Negamax = negamax

Functions

func IterativeDeepening

func IterativeDeepening(cb *board.Board, depth int, stop ...chan bool) (int, board.Move)

Successively call negamax() with increasing depth. It is generally faster than one search to a given depth

Types

type TtEntry

type TtEntry struct {
	Hash                 uint64
	Eval                 int
	Move                 board.Move
	NodeType, Age, Depth uint8
