The extent to which an individual or chance can influence the outcome of a game is a central question in the analysis of games. Consequently, the ability to characterize sources of variation in game outcomes may have significant implications in areas such as game design, law, and multi-agent reinforcement learning. We derive a closed-form expression and estimators for the variance in the outcome of a general multi-agent game that is attributable to a player or chance. We analyze poker hands to…

Measuring Skill in Games with Random Payoffs: Evaluating Legality

Games, such as carnival or electronic/video games, may award prizes in some U.S. states only if the game’s outcome depends sufficiently on skill. Otherwise, the game is classified as a gambling

Fictitious Self-Play in Extensive-Form Games

The first variant of fictitious play is a full-width process that is realization equivalent to its normal-form counterpart and therefore inherits its convergence guarantees, but its computational requirements are linear in time and space rather than exponential.

Finding mixed strategies with small supports in extensive form games

This paper investigates the existence of “small” mixed strategies in extensive form games, and how such strategies can be used to create more efficient algorithms, and constructs the first exponential-time algorithm for finding all equilibria of an arbitrary two- person game in extensiveform.

Open-ended Learning in Symmetric Zero-sum Games

A geometric framework for formulating agent objectives in zero-sum games is introduced, and a new algorithm (rectified Nash response, PSRO_rN) is developed that uses game-theoretic niching to construct diverse populations of effective agents, producing a stronger set of agents than existing algorithms.

Navigating the Landscape of Games

It is shown how network measures applied to so-called response graphs of large-scale games enable the creation of a useful landscape of games, quantifying the relationships between games of widely varying sizes, characteristics, and complexities.

Monte Carlo Sampling for Regret Minimization in Extensive Games

A general family of domain-independent CFR sample-based algorithms called Monte Carlo counterfactual regret minimization (MCCFR) is described, of which the original and poker-specific versions are special cases.

Navigating the landscape of multiplayer games

It is shown how network measures applied to response graphs of large-scale games enable the creation of a landscape of games, quantifying relationships between games of varying sizes and characteristics, and a demonstration leveraging this information to generate new and interesting games.

Beyond Chance? The Persistence of Performance in Online Poker

An analysis into the role of skill in the performance of online poker players, using a large database with hundreds of millions of player-hand observations from real money ring games at three different stakes levels, finds that players whose earlier profitability was in the top (bottom) deciles perform better and are substantially more likely to end up in thetop performance deciles of the following time period.

Flows and Decompositions of Games: Harmonic and Potential Games

A novel flow representation for finite games in strategic form that allows a canonical direct sum decomposition of an arbitrary game into three components, which are referred to as the potential, harmonic, and nonstrategic components is introduced.

Multiagent Systems - Algorithmic, Game-Theoretic, and Logical Foundations

This exciting and pioneering new overview of multiagent systems, which are online systems composed of multiple interacting intelligent agents, i.e., online trading, offers a newly seen computer
