Types

type LogIteration

type LogIteration struct {
	Iteration int       `json:"iteration" yaml:"iteration"`
	Plays     []LogPlay `json:"plays" yaml:"plays"`
	Thread    int       `json:"thread" yaml:"thread"`
}

LogIteration is a struct meant for serializing to a log-file, for debug and other purposes.

type LogPlay

type LogPlay struct {
	Play string `json:"play" yaml:"play"`
	Rack string `json:"rack" yaml:"rack"`
	Pts  int    `json:"pts" yaml:"pts"`
	// Leftover is the equity of the leftover tiles at the end of the sim.
	Leftover float64 `json:"left,omitempty" yaml:"left,omitempty"`
	// Although this is a recursive structure we don't really use it
	// recursively.
	Plies []LogPlay `json:"plies,omitempty" yaml:"plies,omitempty,flow"`
}

LogPlay is a single play.

type SimmedPlay

type SimmedPlay struct {
	sync.Mutex
	// contains filtered or unexported fields
}

func (*SimmedPlay) String

func (sp *SimmedPlay) String() string

type Simmer

type Simmer struct {
	// contains filtered or unexported fields
}

Simmer implements the actual look-ahead search

func (*Simmer) EquityStats

func (s *Simmer) EquityStats() string

func (*Simmer) Init

func (s *Simmer) Init(game *game.Game, aiplayer player.AIPlayer)

func (*Simmer) IsSimming

func (s *Simmer) IsSimming() bool

func (*Simmer) Iterations

func (s *Simmer) Iterations() int

func (*Simmer) PrepareSim

func (s *Simmer) PrepareSim(plies int, plays []*move.Move)

PrepareSim resets all the stats before a simulation.

func (*Simmer) Ready

func (s *Simmer) Ready() bool

func (*Simmer) Reset

func (s *Simmer) Reset()

func (*Simmer) ScoreDetails

func (s *Simmer) ScoreDetails() string

func (*Simmer) SetLogStream

func (*Simmer) SetThreads

func (s *Simmer) SetThreads(threads int)

func (*Simmer) Simulate

func (s *Simmer) Simulate(ctx context.Context) error

Simulate sims all the plays. It is a blocking function.

func (*Simmer) TrimBottom

type Statistic

type Statistic struct {
	// contains filtered or unexported fields
}

Statistic contains statistics per move

func (*Statistic) Mean

func (s *Statistic) Mean() float64

func (*Statistic) Push

func (s *Statistic) Push(val float64)

func (*Statistic) Stdev

func (s *Statistic) Stdev() float64
