BishBosh.Input.EvaluationOptions

AUTHOR

Dr. Alistair Ward

DESCRIPTION

• Defines configurable options related to the evaluation of the game at any instance.
• N.B.: evaluation is distinct from search: evaluation => how one assesses the fitness of candidate moves; search => the order in which one evaluates candidates before selecting on the basis of their fitness.
