Sequential Probabilistic Uncertainty Estimation for Parallel Multi-Agent Reasoning Systems

Tunyu Zhang, Zihao Zhao, Yusong Zhao وآخرون · 2026

LLM-based multi-agent systems (MAS) have attracted growing attention for improving reasoning through interaction among multiple agents. In this work, we focus on parallel multi-agent reasoning systems, where several agents solve the same problem over multiple rounds and aggregate their outputs into a final answer. Desp …

Knossos and Ariadne: Benchmarking and Learning Complete Diagram Topology Extraction with Vision-Language Models

Bangwei Guo, Xujiang Zhao, Shengyu Chen وآخرون · 2026

Structural diagrams are widely used to represent complex systems and relational information across scientific, engineering, procedural, and spatial domains. Recent vision-language models (VLMs) have become increasingly capable of recognizing diagram elements and reasoning about their content, while complete diagram top …

CLIMB: Confidence-Guided Complementary Evidence for Multimodal Retrieval-Augmented Generation

Hang Gao, Wujiang Xu, Zhixing Zhang وآخرون · 2026

Multimodal large language models (MLLMs) have shown strong visual reasoning abilities, but knowledge-intensive visual question answering often requires external textual evidence beyond the image and the model's parametric knowledge. Existing multimodal RAG systems commonly rely on Top-$K$ retrieval or reranking, which …

Turbo Harness: Instance-Adaptive Harness Optimization

Tunyu Zhang, Hao Wang, Kai Xu وآخرون · 2026

Automating the search for effective harnesses is an important step toward enabling agents to recursively self-improve. Existing harness optimizations typically produce a single global harness that is applied uniformly across task instances. However, a harness that works well on average may not be optimal for every inst …

Beyond Solo and Consistency: Vindicating Multi-Agent Debate via Conditional Progressive Pruning

Ruosong Ye, Caiqi Zhang, Jiahao Li وآخرون · 2026

Large Language Model (LLM) based Multi-Agent Debate (MAD) is one of the most effective test time scaling techniques. Through multi-round communication, agents complement each other in knowledge and reasoning and solve tasks that no single member can solve. However, existing MAD frameworks fail to beat strong Single Age …

Opera: A Verbal Critic Framework for Long-horizon Coding Agents

Kai Mei, Zhiyuan Hu, Yutong Dai وآخرون · 2026

Long-horizon coding agents need timely corrections, yet feedback can be ineffective or even harmful when it misjudges ongoing work or fails to address the underlying problem. Existing critics focus on evaluating trajectories and generating feedback, but rarely track what happens after feedback is delivered. We present …
