AUTHOR

Dr. Alistair Ward

DESCRIPTION

• Quantifies a game, & therefore the sequence of moves applied.
• The fitness & its breakdown into constituent criterion-values, are also recorded.

Types

Type-synonyms

type OpenInterval x y = (Maybe (QuantifiedGame x y), Maybe (QuantifiedGame x y))

• The open interval in which to search for better solutions.
• N.B.: Nothing is interpreted as unbounded.

Data-types

data QuantifiedGame x y

The selected game & the criteria against which it was quantified.

Accessors

getLastTurn :: QuantifiedGame x y -> Turn x y

-> QuantifiedGame x y

-> [Turn x y]

Drop the specified number of plies from the start of the chronological sequence, leaving the most recent.

Mutators

negateFitness :: QuantifiedGame x y -> QuantifiedGame x y

Represent the fitness of the game resulting from a future move by the opponent, from the perspective of the current player.

negateInterval :: OpenInterval x y -> OpenInterval x y

Reflect the interval about zero.
