Zero-Sum Mindset & Its Discontents
… feature that presents a barrier to progress: zero-sum thinking. Zero-sum thinking is a tendency to perceive a situation as a zero-sum game, where for one player to win, another must lose. In a zero-sum game, winnings exist in a fixed amount. Therefore, any gain for one party must come at the …

Zero-sum problems in finite cyclic groups
… of combinatorial number theory referred to as zero-sum theory. A zero-sequence in a finite cyclic group G is said to have the basic property if it is equivalent under group automorphism to one which has sum precisely IGI when this sum is viewed as an integer. This thesis investigates two major …

Multi-Player Zero-Sum Markov Games with Networked Separable Interactions
… a new class of Markov games, (multi-player) zero-sum Markov Games with Networked separable interactions (zero-sum NMGs), to model the local interaction structure in non-cooperative multi-agent sequential decision-making. We define a zero-sum NMG as a model where the payoffs of the auxiliary …

Two Approaches to Non-Zero-Sum Stochastic Differential Games of Control and Stopping
… differential equation (BSDE) - to solve non-zero-sum stochastic differential games in which all players can control and stop the reward streams of the games. Existence of equilibrium stopping rules is proved under some assumptions. The martingale part provides an equivalent martingale …

The complexity of Nash equilibria in multiplayer zero-sum games and coordination games
… theorem to the class of separable multiplayer zero-sum games, introduced in [Bregman and Fokin 1998]. These games are polymatrix-that is, graphical games in which every edge is a two-player game between its endpoints-in which every outcome has zero total sum of players' payoffs. Our …

Gas network optimisation using Nash equilibria derived from dynamic non-cooperative non-zero sum game theory
… sourcing and transmission operations.The consumers network/demand off-takes are shown to be the key elementsof the framework which maintain both the physical and economic integrity of theNTS.A conceptual framework is developed to implement the design to form HERO— an experimental economic …

The cybernetics of nonzero sum games – the prisoner's dilemma reinterpreted as a pure conflict game with nature, with empirical applications
… solution concept is developed for n-player, nonzero sum games. The solution concept is based in reinterpreting the n-player nonzero sum game into 2-player zero sum games. The n-player nonzero sum game is first rewritten as an n + 1 player coalition game. The definition of zero sum payment is …

Some problems in discounted stochastic games
… stochastic games. Second, the thesis examines zero-sum stochastic games with sepa-rable discounting. Using the concept of supergames, it is demonstrated that every zero-sum finite stochastic game with separable discounting admits a value. Furthermore, it is established that, under certain …

ENDING AN ENEMY: UNITED STATES–IRAN RELATIONS
… described by U.S. leaders as an intractable, zero-sum problem. In this view, the solution is to collapse the Islamic Republic by military threats and unyielding economic pressure. Since 1979, presidents of both parties have pursued this two-tool campaign with similar results. This research …

Securing the Korean Peninsula with an Armed Nuclear North Korea: Identifying Pathways by Examining Past and Current Negotiations
… on the Korean peninsula are best described as zero sum. Central to the challenge of achieving détente on the peninsula is the ability to shift actors away from zero-sum behavior to that of positive-sum relationship to achieve gains that foster iterative interactions. As these iterative …

Barrier Coverage: Deploying Robot Guards to Prevent Intrusion
… use these barriers together with noncooperative zero-sum game theory to construct partial barriers. These are strategies for minimizing undetected intrusion when there is a limitation on available guard resources. We give equilibrium strategies for guards and intruder for the above three guard …

A Minimax Approach for Learning Gaussian Mixtures
… the distribution of observed samples through a zero-sum game between two machine players, a generator and a discriminator. While GANs achieve great success in learning the complex distribution of image, sound, and text data, they perform suboptimally in learning multi-modal distributionlearning …

A counter-example to Karlin's strong conjecture for fictitious play
… is a natural dynamic for equilibrium play in zero-sum games, proposed by Brown , and shown to converge by Robinson . Samuel Karlin conjectured in 1959 that fictitious play converges at rate O(t- 1/ 2) with respect to the number of steps t. We disprove this conjecture by showing that, when the …

Strategizing against online learners in normal form repeated games
… the learner’s behavior. We study this setting in zero-sum and general-sum games. In zero-sum games, we provide algorithms for the optimizer that can efficiently exploit a learner that employs a specific online learning algorithm in discrete and continuous-time dynamics. Specifically, the learner …

Inference of Cyber Threats, Vulnerabilities, and Mitigations to Enhance Cybersecurity Simulations
… attackers and defenders on a given network in a zero-sum game. We apply coevolution in a novel multi-step feedback framework to improve performance in modelling attacks, and find that allowing attackers to dynamically select their attack strategies improves their payoff.

Critiquing Atomistic Individualism in Law: Rosenzweig's Beloved Soul as Open and Relational Subject

Unifying Strategic Military Force Design and Operational Warfighting: A Stochastic Game Approach
… stochastic game (CSG), a two-player, discounted, zero-sum stochastic game model for dynamic operational planning in military campaigns. Then, at the strategic level, we use this representation to evaluate force designs directly in the operational contexts where they may be employed in a future …

On Solving Larger Games: Designing New Algorithms Adaptable to Deep Reinforcement Learning
