Functions

func AlphaBeta

func AlphaBeta(state *hex.State, timeToRun time.Duration, createTree bool,
	gridChan chan []uint32, patChan chan []int, resultChan chan [2][]int,
	getEstimatedValue func(s *Sample) float64, subtype string) (*hex.Action, *tree.Tree)

AlphaBeta runs search with AB pruning to select the next action to be taken. In addition to the selected action it returns the tree that was constructed during the last AB search (if wanted).

func GetEstimateFunction

func GetEstimateFunction(subtype string) func(s *Sample) float64

GetEstimateFunction returns a function that will be used for evaluating states

Types

type NodeValue

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

NodeValue stores a hex state and its estimated value, obtained by negamax algorithm with AB pruning. comment is used for debugging purposes

func CreateAbNodeValue

func CreateAbNodeValue(state *hex.State, value float64, comment string) *NodeValue

CreateAbNodeValue creates a new NodeValue with given state and its estimated value

func (NodeValue) MarshalJSON

func (anv NodeValue) MarshalJSON() ([]byte, error)

MarshalJSON implements Marshaler interface It returns NodeValue in JSON format

func (NodeValue) String

func (anv NodeValue) String() string
