Let's Think in Two Steps: Mitigating Agreement Bias in MLLMs with Self-Grounded Verification

This paper identifies a pervasive "agreement bias" in Multimodal LLM verifiers that causes them to over-validate agent behavior, and proposes a lightweight Self-Grounded Verification (SGV) method that significantly improves failure detection and task completion across web navigation, computer use, and robotics by decoupling prior generation from trajectory evaluation.

Multi-Agent DRL for V2X Resource Allocation: Disentangling Challenges and Benchmarking Solutions

This paper addresses the lack of systematic evaluation in Multi-Agent Deep Reinforcement Learning for C-V2X resource allocation by introducing a disentangled benchmark suite of interference games and diverse datasets to isolate specific challenges, ultimately identifying policy robustness and generalization across vehicular topologies as the primary hurdle and demonstrating the superiority of actor-critic methods over value-based approaches.

What Do Agents Think One Another Want? Level-2 Inverse Games for Inferring Agents' Estimates of Others' Objectives

This paper proposes a novel level-2 inverse game framework that infers agents' estimates of each other's objectives to address the limitations of traditional level-1 methods in decentralized scenarios, demonstrating through theory and experiments that accounting for these mutual misalignments is crucial for accurately predicting strategic interactions.

The Yokai Learning Environment: Tracking Beliefs Over Space and Time

This paper introduces the Yokai Learning Environment (YLE), a new open-source benchmark for zero-shot coordination that overcomes the saturation of the Hanabi Learning Environment by requiring agents to track moving cards and reason under ambiguous hints, thereby revealing that current state-of-the-art methods fail to maintain consistent internal models when paired with unseen partners.

Mindstorms in Natural Language-Based Societies of Mind

This paper proposes Natural Language-Based Societies of Mind (NLSOMs), a modular framework where large multimodal neural networks communicate via natural language to solve complex AI tasks more effectively than single models, while also exploring the emerging social, economic, and structural challenges of scaling these heterogeneous societies to include billions of agents.

Multi-Agent Memory from a Computer Architecture Perspective: Visions and Challenges Ahead

This position paper reframes multi-agent memory as a computer architecture challenge by proposing a three-layer hierarchy and identifying critical protocol gaps, with a specific focus on resolving multi-agent memory consistency as the primary obstacle to building reliable and scalable collaborative systems.

Sequential Causal Normal Form Games: Theory, Computation, and Strategic Signaling

This paper extends Causal Normal Form Games to sequential settings by introducing Sequential Causal Multi-Agent Systems, but its comprehensive theoretical and empirical analysis reveals that, under standard rational assumptions, these causal frameworks offer no welfare advantage over classical Stackelberg equilibrium, thereby highlighting a fundamental incompatibility between rational choice and causal reasoning benefits in current game-theoretic models.

The Coordination Gap: Alternation Metrics for Temporal Dynamics in Multi-Agent Battle of the Exes

This paper introduces temporally sensitive Alternation (ALT) metrics to reveal that conventional outcome-based evaluations can severely mischaracterize multi-agent coordination, as demonstrated by Q-learning agents in a Battle of the Exes variant that achieve high traditional fairness scores but perform significantly worse than random baselines in actual turn-taking dynamics.
