DESCRIPTION
- Defines the value for each type of piece, of occupying different squares.
- This metric includes aspects of both control of the centre, & material advantage, in that a side's score can increase either by occupying more valuable squares or simply by having more pieces.
- N.B.: the evaluation of fitness by "material" COULD be entirely built into these tables, so that the average value for a
Queen
is ~9 times that for aPawn
, but under these circumstances a non-zero material value for aKing
must be arbitrarily chosen. - N.B. The normal & end-game phases are typically represented by independent instances.
