-EPSILON = (1 + RANDOM_MAX)*options.ABS_TOL
-"""
-This is the tolerance constant including fudge factors that we use to
-determine whether or not two numbers are equal in tests.
-
-Often we will want to compare two solutions, say for games that are
-equivalent. If the first game value is low by ``ABS_TOL`` and the second
-is high by ``ABS_TOL``, then the total could be off by ``2*ABS_TOL``. We
-also subject solutions to translations and scalings, which adds to or
-scales their error. If the first game is low by ``ABS_TOL`` and the
-second is high by ``ABS_TOL`` before scaling, then after scaling, the
-second could be high by ``RANDOM_MAX*ABS_TOL``. That is the rationale
-for the factor of ``1 + RANDOM_MAX`` in ``EPSILON``. Since ``1 +
-RANDOM_MAX`` is greater than ``2*ABS_TOL``, we don't need to handle the
-first issue mentioned (both solutions off by the same amount in opposite
-directions).
