Constants

const NegInf = math.MinInt16 + 2

Both constants are negatable and +1able without overflowing

const PosInf = math.MaxInt16 - 1

const QuiesceCutoffDepth = 5

Variables

var DefaultSearchThreads int = runtime.NumCPU()

var HistoryMap map[uint64]int = make(map[uint64]int)

Used to keep track of positions that have occurred in the game

Functions

func CalculateAllowedTime

func CalculateAllowedTime(b *dragontoothmg.Board, ourtime int, opptime int, ourinc int, oppinc int) int

func Search

func Search(board *dragontoothmg.Board, halt <-chan bool, stop *bool)

The main entrypoint for the search. Spawns the appropriate number of threads, and prints the results (including pv and bestmove).

func SearchTimeout

func SearchTimeout(halt chan<- bool, ms int, alreadyStopped *bool)

After a certain period of time, sends a signal to halt the search, if it has not already been sent. Also prints the best move. If the sleep time is 0, does nothing. The bool pointer alreadyStopped should be the same as the one given to Search().
