Interdependent defense games with applications to Internet security at the level of autonomous systems

Chan, Hau; Ceyko, Michael; Ortiz, Luis - In: Games 8 (2017) 1, pp. 1-60

instances of IDD games based on the real-world Internet-derived graph at the level of autonomous systems (≈27 K nodes and ≈100 K … edges as measured in March 2010 by the DIMES project). We call such games Internet games. We introduce and empirically …-generated instances of Internet games. In general, preliminary experiments applying our proposed heuristics are promising. Our experiments …

Conflict without an apparent cause

Mathews, Timothy; Bagchi, Aniruddha - In: Games 10 (2019) 4/39, pp. 1-12

A game-theoretic model of repeated interaction between two potential adversaries is analyzed to illustrate how conflict could possibly arise from rational decision-makers endogenously processing information, without any exogenous changes to the fundamentals of the environment. This occurs as a...

A game-theoretic approach for modeling competitive diffusion over social networks

Jafari, Shahla; Navidi, Hamidreza - In: Games 9 (2018) 1/8, pp. 1-18

In this paper, we consider a novel game theory model for the competitive influence maximization problem. We model this problem as a simultaneous non-cooperative game with complete information and rational players, where there are at least two players who are supposed to be out of the network and...

Dynamic pricing decisions and seller-buyer interactions under capacity constraints

Mak, Vincent; Rapoport, Amnon; Gisches, Eyran J. - In: Games 9 (2018) 1/10, pp. 1-23

Focusing on sellers’ pricing decisions and the ensuing seller-buyer interactions, we report an experiment on dynamic pricing with scarcity in the form of capacity constraints. Rational expectations equilibrium solutions are constructed and then tested experimentally with subjects assigned the...

Ethics, morality, and game theory

Alfano, Mark; Rusch, Hannes; Uhl, Matthias - In: Games 9 (2018) 2/20, pp. 1-4

Ethics is a field in which the gap between words and actions looms large. Game theory and the empirical methods it inspires look at behavior instead of the lip service people sometimes pay to norms. We believe that this special issue comprises several illustrations of the fruitful application of...

Bifurcation mechanism design : from optimal flat taxes to better cancer treatments

Yang, Ger; Basanta, David; Piliouras, Georgios - In: Games 9 (2018) 2/21, pp. 1-38

Small changes to the parameters of a system can lead to abrupt qualitative changes of its behavior, a phenomenon known as bifurcation. Such instabilities are typically considered problematic, however, we show that their power can be leveraged to design novel types of mechanisms. Hysteresis...

Game theory of tumor-stroma interactions in multiple myeloma : effect of nonlinear benefits

Sartakhti, Javad Salimi; Manshaei, Mohammad Hossein; … - In: Games 9 (2018) 2/32, pp. 1-11

Cancer cells and stromal cells often exchange growth factors with paracrine effects that promote cell growth: a form of cooperation that can be studied by evolutionary game theory. Previous models have assumed that interactions between cells are pairwise or that the benefit of a growth factor is...

How to analyze models of nonlinear public goods

Archetti, Marco - In: Games 9 (2018) 2/17, pp. 1-15

Public goods games often assume that the effect of the public good is a linear function of the number of contributions. In many cases, however, especially in biology, public goods have nonlinear effects, and nonlinear games are known to have dynamics and equilibria that can differ dramatically...

Evolutionary game theory : a renaissance

Newton, Jonathan - In: Games 9 (2018) 2/31, pp. 1-67

Economic agents are not always rational or farsighted and can make decisions according to simple behavioral rules that vary according to situation and can be studied using the tools of evolutionary game theory. Furthermore, such behavioral rules are themselves subject to evolutionary forces....

Security from the adversary's inertia-controlling convergence speed when playing mixed strategy equilibria

Wachter, Jasmin; Rass, Stefan; König, Sandra - In: Games 9 (2018) 3/59, pp. 1-15

Game-theoretic models are a convenient tool to systematically analyze competitive situations. This makes them particularly handy in the field of security where a company or a critical infrastructure wants to defend against an attacker. When the optimal solution of the security game involves...
