Functions

func CalculateShanten

func CalculateShanten(tiles34 []int, isOpen bool) int

根据手牌计算向听数 tiles34 手牌 isOpen 是否副露，未副露的手牌会考虑七对子 TODO: 这样好吗？

func CalculateShantenWithImproves14

func CalculateShantenWithImproves14(tiles34 []int, isOpen bool) (shanten int, waitsWithImproves WaitsWithImproves14List, incShantenResults WaitsWithImproves14List)

14 张牌，计算向听数、进张、改良、向听倒退等

func CalculateShantenWithoutChitoitsu

func CalculateShantenWithoutChitoitsu(tiles34 []int) int

func CountOfTiles

func CountOfTiles(tiles []int) (count int)

func CountPairs

func CountPairs(tiles34 []int) (pairs int)

func MustStrToTiles34

func MustStrToTiles34(tiles string) []int

func NumberToChineseShanten

func NumberToChineseShanten(num int) string

func StrToTile34

func StrToTile34(tile string) (tile34 int, err error)

func StrToTiles34

func StrToTiles34(tiles string) (num int, tiles34 []int, err error)

e.g. "22m 24p" => (4, [0, 2, 0, 0, ...,0, 10, 12])

func TilesToMergedStr

func TilesToMergedStr(tiles []int) (res string)

[0, 2, 9] => "13m 1p"

func TilesToMergedStrWithBracket

func TilesToMergedStrWithBracket(tiles []int) (res string)

[0, 2, 9] => "[13m 1p]"

Types

type Improves

type Improves map[int]Waits

map[改良牌]进张

type Waits

type Waits map[int]int

map[进张牌]剩余数

func CalculateShantenAndWaits13

func CalculateShantenAndWaits13(tiles34 []int, isOpen bool) (shanten int, waits Waits)

13 张牌，计算向听数和进张

func (Waits) FixCountsWithLeftCounts

func (w Waits) FixCountsWithLeftCounts(leftCounts []int)

func (Waits) ParseIndex

func (w Waits) ParseIndex() (allCount int, indexes []int)

func (Waits) String

func (w Waits) String() string

type WaitsWithImproves13

type WaitsWithImproves13 struct {
	// 手牌
	Tiles34 []int

	// 向听数
	Shanten int

	// 进张：摸到这张牌可以让向听数前进
	Waits Waits

	// map[进张牌]向听前进后的进张数（这里让向听前进的切牌是最优切牌，即让向听前进后的进张数最大的切牌）
	NextShantenWaitsCountMap map[int]int

	// 改良：摸到这张牌虽不能让向听数前进，但可以让进张变多
	Improves Improves

	// 改良情况数
	ImproveWayCount int

	// 对于每张牌，摸到之后的手牌进张数（如果摸到的是 Waits 中的牌，则进张数视作摸到之前的进张数）
	ImproveWaitsCount34 []int

	// 在没有摸到进张时的改良进张数的加权均值
	AvgImproveWaitsCount float64

	// 向听前进后的进张数的加权均值
	AvgNextShantenWaitsCount float64
}

13 张手牌的分析结果
