Regret Testing: Learning to Play Nash Equilibrium without Knowing You Have an Opponent.
Published 2006“…We demonstrate a family of simple, radically uncoupled learning rules whose period-by-period behavior comes arbitrarily close to Nash equilibrium behavior in any finite two-person game.…”

Fast Convergence in Population Games
Published 2011“…A stochastic learning dynamic exchibits fast convergence in a population game if the expected waiting time until the process comes near a Nash equilibrium is bounded above for all sufficiently large populations. …”

Learning by trial and error.
Published 2009“…This rule, called interactive trial and error learning, implements Nash equilibrium behavior in any game with generic payoffs and at least one pure Nash equilibrium.…”

Learning efficient Nash equilibria in distributed systems
Published 2010“…We propose a variant of log linear learning that is completely uncoupled and that selects an efficient pure Nash equilibrium in all generic n-person games that possess at least one pure Nash equilibrium. …”

Learning to Play Nash.
Published 2000“…Although there exist rules that converge to Nash equilibrium for special classes of games (like fictuous play in zero-sum games), it is an open question whether players can learn to play Nash in general games without assuming that they have a prior knowledge of their opponent's strategies. …”

Published 2008“…This paper introduces a simple version of this idea, called interactive trial and error learning, which has the property that it implements Nash equilibrium behavior in any game with generic payoffs and at least one pure Nash equilibrium. …”

Payoff-based dynamics for multiplayer weakly acyclic games.
Published 2009“…We introduce three different payoff-based processes for increasingly general scenarios and prove that, after a sufficiently large number of stages, player actions constitute a Nash equilibrium at any stage with arbitrarily high probability. …”

The Possible and the Impossible in Multi-Agent Learning.
Published 2007“…The paper surveys recent work on learning in games and delineates the boundary between forms of learning that lead to Nash equilibrium and forms that lead to weaker notions of equilibrium (or none at all).…”

On the Limits to Rational Learning.
Published 2002“…That is, under any learning rule--including Bayesian updating of common priors--the players' strategies fail to come close to Nash equilibrium with probability one. Furthermore at least one of them is unable to predict the behavior of the other in an asymptotic sense. …”

Learning in a black box: trial-and-error in voluntary contributions games
Published 2013“…These features are clearly present when players have no information about the game; but also when players have full informaiton. Convergence to Nash equilibrium occurs at about the same rate in both situations.…”

Learning Dynamics in Games with Stochastic Perturbations.
Published 1995“…It is shown, using results from stochastic approximation theory, that for 2 x 2 games it converges almost surely to a point that lies close to a stable Nash equilibrium, whether pure or mixed. This generalizes a result of Fudenberg and Kreps, who demonstrate convergence when the game has a unique mixed equilibrium. …”

Learning in a black box
Published 2016“…Theory shows that even when players have no such information, there are simple payoff-based learning rules that lead to Nash equilibrium in many types of games. A key feature of these rules is that subjects search differently depending on whether their payoffs increase, stay constant or decrease. …”

Cost Allocation, Demand Revelation, and Core Implementation.
Published 1998“…We propose a simple demand revelation mechanism in which potential customers bid to be served and the regulator accepts a set of bids that maximizes revenues net of costs. In a strong Nash equilibrium, the mechanism reveals the efficient set of customers to serve and covers the costs of serving them, possibly with a surplus for the producer. …”
