DESCRIPTION

• The relative values of the various ranks of chess-piece.
• Chess-piece relative values

Types

Data-types

data RankValues rankValue

• The constant value associated with each rank; the higher, the more valuable it is considered to be.
• N.B.: only relative values are significant; the absolute value associated with any rank is irrelevant, but typically Pawn = 1.
• CAVEAT: a King can never be taken, but assigning the value infinity creates problems, so typically it has the value 0.

Instances

Eq rankValue => Eq (RankValues rankValue)

Methods

(==) :: RankValues rankValue -> RankValues rankValue -> Bool

(/=) :: RankValues rankValue -> RankValues rankValue -> Bool

Read rankValue => Read (RankValues rankValue)

Methods

readsPrec :: Int -> ReadS (RankValues rankValue)

readList :: ReadS [RankValues rankValue]

readPrec :: ReadPrec (RankValues rankValue)

readListPrec :: ReadPrec [RankValues rankValue]

Show rankValue => Show (RankValues rankValue)

Methods

showsPrec :: Int -> RankValues rankValue -> ShowS

show :: RankValues rankValue -> String

showList :: [RankValues rankValue] -> ShowS

NFData rankValue => NFData (RankValues rankValue)

Methods

rnf :: RankValues rankValue -> ()

(Fractional rankValue, Ord rankValue, Show rankValue) => Default (RankValues rankValue)

Methods

def :: RankValues rankValue

(Fractional rankValue, XmlPickler rankValue, Ord rankValue, Show rankValue) => XmlPickler (RankValues rankValue)

Methods

xpickle :: PU (RankValues rankValue)

Real rankValue => ShowFloat (RankValues rankValue)

Methods

showsFloat :: (Double -> ShowS) -> RankValues rankValue -> ShowS

Constants

tag :: String

Functions

findRankValue :: Rank -> RankValues rankValue -> rankValue

Query.

calculateMaximumTotalValue :: Num rankValue => RankValues rankValue -> rankValue

• The maximum total rank-value one side can have.
• CAVEAT: assumes that zero pieces have been captured, all Pawns have been queened, & that this is the most valuable rank of piece.

Constructor

fromAssocs :: (Fractional rankValue, Ord rankValue, Show rankValue) => [(Rank, rankValue)] -> RankValues rankValue
