Toward an enhanced scalability framework for human‐multi‐agent teams
AI Magazine, Volume 47, Issue 4, Winter 2026.Abstract As autonomous systems become increasingly capable, the deployment of Human‐Multi‐Agent Teams (HMATs) offers immense potential for executing complex, decentralized tasks. However, realizing this potential is constrained by a critical bottleneck: the cognitive and supervisory capacity of the human operator.

Discovering Governing Spatial Interaction Equations in Dynamic Urban Systems
Transactions in GIS, Volume 30, Issue 7, November 2026.ABSTRACT Governing equations are fundamental for describing and predicting dynamic urban geographic systems. Unlike physical systems guided by first principles, urban spatiotemporal phenomena emerge from coupled geographic processes that lack deterministic theoretical foundations, making the discovery of governing equations elusive and largely ...
