For Dynamic Games
For dynamic (extensive form) games, McKelvey and Palfrey defined agent quantal response equilibrium (AQRE). AQRE is somewhat analogous to subgame perfection. In an AQRE, each player plays with some error as in QRE. At a given decision node, the player determines the expected payoff of each action by treating their future self as an independent player with a known probability distribution over actions.
As in QRE, in a AQRE every strategy is used with nonzero probability. This provides an additional advantage of AQRE over perfectly rational solution concepts. Since every path is followed with some probability, there is no concern about defining beliefs "off the equilibrium path".

Famous quotes containing the words dynamic and/or games:
“We Americans have the chance to become someday a nation in which all radical stocks and classes can exist in their own selfhoods, but meet on a basis of respect and equality and live together, socially, economically, and politically. We can become a dynamic equilibrium, a harmony of many different elements, in which the whole will be greater than all its parts and greater than any society the world has seen before. It can still happen.”
—Shirley Chisholm (b. 1924)
“In the past, it seemed to make sense for a sportswriter on sabbatical from the playpen to attend the quadrennial hawgkilling when Presidential candidates are chosen, to observe and report upon politicians at play. After all, national conventions are games of a sort, and sports offers few spectacles richer in low comedy.”
—Walter Wellesley (Red)
