Dual-Interaction-Aware Cooperative Control Strategy for Alleviating Mixed Traffic Congestion

This paper proposes a Dual-Interaction-Aware Cooperative Control (DIACC) strategy based on Multi-Agent Reinforcement Learning, which integrates decentralized decision-making, centralized value estimation, and a novel reward design to effectively alleviate mixed traffic congestion by distinguishing between cooperative and observational vehicle interactions.

Graph-theoretic Agreement Framework for Multi-agent LLM Systems

This paper establishes a rigorous graph-theoretic framework that maps Transformer cross-entropy log-odds to signed Laplacians to analyze consensus stability in multi-agent LLM systems, demonstrating how structural balance theory identifies reasoning oscillations caused by unobservable latent states and proposing chordal graph topologies with spectral perturbations to deterministically resolve these deadlocks.

Assessing Risks of Large Language Models in Mental Health Support: A Framework for Automated Clinical AI Red Teaming

This paper introduces a simulation-based clinical red teaming framework that pairs AI psychotherapists with dynamic patient agents to evaluate mental health support systems, revealing critical safety gaps such as the validation of delusions and failure to de-escalate suicide risk in AI agents tested against Alcohol Use Disorder scenarios.

GRAND: Guidance, Rebalancing, and Assignment for Networked Dispatch in Multi-Agent Path Finding

The paper proposes GRAND, a hybrid hierarchical algorithm that combines reinforcement learning-based graph guidance with minimum-cost flow rebalancing and local assignment to achieve up to 10% higher throughput than state-of-the-art schedulers for large-scale, lifelong multi-agent pickup-and-delivery tasks while maintaining real-time execution.

Conflict-Based Search as a Protocol: A Multi-Agent Motion Planning Protocol for Heterogeneous Agents, Solvers, and Independent Tasks

This paper proposes a Conflict-Based Search (CBS) protocol that enables efficient, collision-free multi-agent motion planning for heterogeneous teams of robots with independent tasks by utilizing a central planner that coordinates diverse single-agent solvers—ranging from traditional algorithms to learning-based methods—through a standardized space-time constraint API.
