Point It, Strike It: Direction-Conditioned Dynamic Manipulation of Deformable Linear Objects

Yi Yang, Xiang Fei, Lehong Wang et al. · 2026

Goal-conditioned dynamic manipulation of deformable linear objects has mainly specified goals as positions for a rope tip to reach. Many tasks, however, depend on how the tip arrives. We therefore study single-swing rope striking with goals that specify the tip's 3D position and arrival direction, across the workspace …

The Missing Primitive: Diagnosing and Repairing Mathematical Reasoning in Large Language Models

Shuo Xing, Zilin Dai, Chengyuan Qian et al. · 2026

While Large Language Models (LLMs) have demonstrated striking capabilities on frontier mathematical problems, it remains unclear whether they possess the structural mathematical understanding underlying their solutions. In this paper, we take a first step toward systematically studying mathematical understanding in LLM …
