Analysis of the two-for-one swap heuristic for approximating the maximum independent set in a k-polymatroid

Adrian Calinescu, Gruia Calinescu

Let f:2^N --> \cZ^+ be a polymatroid (an integer-valued non-decreasing submodular set function with f(emptyset) = 0). A k-polymatroid satisfies that f(e) <= k for all e in N. We ca…

Facts Without Rules: Boundary Metadata Collapse in Multi-Agent LLM Handoffs

Yian Wang, Agam Goyal, Eshwar Chandrasekharan +1

Multi-agent LLM systems often coordinate by compressing an upstream interaction into a handoff artifact that downstream agents treat as shared state. We show that this handoff step…

Momentum-resolved EELS study of collective charge excitations in 1-TaS

Farzaneh Hoveyda-Marashi, Xuefei Guo, Caitlin Kengle +5

We use momentum-resolved electron energy-loss spectroscopy (M-EELS) to study the low-energy charge excitations of 1-TaS across the nearly commensurate-to-commensurate charge…
