|Title:||The spread of exploitative behavior in social networks and associated longitudinal effects on global topology|
|Seminar:||Applied Algebra and Network Theory Seminar|
|Speaker:||Chris Griffin, Penn State|
|We present a game-theoretic model for the spread of noncooperative behavior in online social networks. We use a two-strategy prisoner's dilemma framework wherein each player's behavior is classified as normal (cooperate) or abusive (defect) and pairwise interactions between linked players yield a unique payoff to each according to an associated payoff matrix. Player strategies evolve by imitation, as each player mimics successful behavior observed in his immediate neighborhood. Network structure evolves in parallel and is a function of strategy, as players may choose to establish new ties or sever existing ones to increase their payoff. We prove convergence of individual behavior over time to a final strategy vector as well as convergence of network structure to a final pairwise stable network state. Joint work with Sarah Rajtmajer, Derek Mikesell and Anna Squicciarini.|
