epsilon-equilibrium:
(Usually written with a true epsilon character.)
In a noncooperative game, for any small positive number epsilon, an
epsilon-equilibrium is a profile of totally mixed strategies such that
each player gives more probability weight than epsilon only to strategies that

For a more formal definition see sources. This is a rough paraphrase.
