Hyperedge approximation for stochastic processes on higher-order networks
Anzhi Sheng, Alex McAvoy, Ye Tian +3
Graphs are a standard framework for describing dynamical processes shaped by pairwise interactions among agents. But many systems involve interactions in groups of three or more ag…
Meeting times on graphs in near-cubic time
Alex McAvoy
The expected meeting time of two random walkers on an undirected graph of size , where at each time step one walker moves and the process stops when they collide, satisfies a sy…
Strategy evolution on temporal hypergraphs
Xiaochen Wang, Lei Zhou, Alex McAvoy +2
Individuals interact and cooperate in structured systems. Many studies represent this structure using static networks, where each link represents a permanent connection between two…
Expectation-enforcing strategies for repeated games
Nikos Dimou, Alex McAvoy
Originating in evolutionary game theory, the class of "zero-determinant" strategies enables a player to unilaterally enforce linear payoff relationships in simple repeated games. A…
PropensityBench: Evaluating Latent Safety Risks in Large Language Models via an Agentic Approach
Udari Madhushani Sehwag, Shayan Shabihi, Alex McAvoy +4
Recent advances in Large Language Models (LLMs) have sparked concerns over their potential to acquire and misuse dangerous or high-risk capabilities, posing frontier risks. Current…
Behavioral alignment in social networks
Yu Xia, Alex McAvoy, Qi Su
The orderly behaviors observed in large-scale groups, such as fish schooling and the organized movement of crowds, are both ubiquitous and essential for the survival and stability…
