A static evaluation function evaluates a position without doing any search.

Example 1: Chess

e(p) = (sum of values of Max's pieces)
         - (sum of values of Min's pieces)
         + k * (degree of control of the center)

Example 2: Tic-tac-toe

e(p) = nrows(Max) - nrows(Min)
where nrows(i) is the number of complete rows, columns, or diagonals that are still open for player i.
