TERMS-Bench: Diagnosing LLM Negotiation Agents Beyond Deal Rate

Erica Zhang, Fangzhao Zhang, Aneesh Pappu +5

Negotiation is a central mechanism of economic exchange, shaping markets, procurement, labor agreements, and resource allocation. It is also a canonical testbed for agentic languag…

Optimizer-Induced Mode Connectivity: From AdamW to Muon

Fangzhao Zhang, Sungyoon Kim, Erica Zhang +2

Mode connectivity has been widely studied, yet the role of the optimizer remains underexplored. We revisit it through optimizer-induced implicit regularization, asking how connecti…

Learning When to Trust LLM Priors: A Validated Framework for Semantic Prior Integration

Erica Zhang, Naomi Sagan, Danny Tse +3

Large language models (LLMs) encode rich semantic knowledge that can be useful for supervised learning, but their outputs are unreliable as statistical priors: they may be noisy, m…

AlgoTune: Can Language Models Speed Up General-Purpose Numerical Programs?

Ori Press, Brandon Amos, Haoyu Zhao +21

Despite progress in language model (LM) capabilities, evaluations have thus far focused on models' performance on tasks that humans have previously solved, including in programming…

Solving Large Multicommodity Network Flow Problems on GPUs

Fangzhao Zhang, Stephen Boyd

We consider the all-pairs multicommodity network flow problem on a network with capacitated edges. The usual treatment keeps track of a separate flow for each source-destination pa…

Newton Meets Marchenko-Pastur: Massively Parallel Second-Order Optimization with Hessian Sketching and Debiasing

Elad Romanov, Fangzhao Zhang, Mert Pilanci

Motivated by recent advances in serverless cloud computing, in particular the "function as a service" (FaaS) model, we consider the problem of minimizing a convex function in a mas…
