Gate control improves routing efficiency for periodic traffic

Traffic movement on highways and data packet transmission across the Internet serve as prototypical examples of collective dynamical behavior in complex systems. Although enhancing traffic flow in complex networks has been extensively investigated, most existing studies focus on single-queue models. In this paper, we i...

Reinforcement Learning for Graph Generation under a Hard Assortativity Constraint

It is shown that a reinforcement learning framework can drive a graph through degree-preserving rewirings to satisfy a prescribed assortativity, which characterizes the degree--degree correlation of adjacent nodes, establishing reinforcement learning as a practical paradigm for hard-constrained graph generation.
