Agents on the Rise: Navigating Complex Systems from Markets to Medical Imaging

Papers about agents published in arXiv.org on June 24, 2025

Recent research highlights the burgeoning power and versatility of AI agents across diverse domains. From navigating the complexities of economic markets and controlling multi-robot systems to tackling challenges in medical image analysis and even influencing the creative output of large language models, agents are proving to be a powerful paradigm for tackling complex, dynamic problems. A collection of recent pre-print papers on arXiv showcases this trend, offering insights into the design, analysis, and application of agentic systems.

One major theme resonating across these papers is the increasing sophistication of multi-agent systems. Instead of single, monolithic AI entities, researchers are exploring the benefits of decentralized, collaborative agents, each with specialized roles and learning capabilities. This approach mirrors real-world scenarios, whether it’s multiple robots collaborating on a construction site or contour points in medical images acting as individual agents to refine segmentation.

Another key theme is the focus on understanding and controlling agent behavior. As agents become more autonomous and interact with complex environments and each other, predicting and ensuring desirable outcomes becomes paramount. This involves borrowing tools from game theory, dynamical systems, and control theory to analyze stability, convergence, and safety.

Furthermore, the papers demonstrate the growing integration of Large Language Models (LLMs) into agent architectures, leveraging their natural language understanding and generation capabilities to enhance reasoning, collaboration, and problem-solving.

Let’s delve into some of the key contributions and developments presented in these papers:

Navigating Economic Landscapes and Strategic Interactions

The paper “Agentic Markets: Game Dynamics and Equilibrium in Markets with Learning Agents” (http://arxiv.org/pdf/2506.18571v1) provides a foundational analysis of markets populated by autonomous, learning agents. A central contribution is the framework for analyzing game dynamics using dynamical systems theory, specifically focusing on projected gradient and no-regret learning algorithms. The paper explores when and how these learning agents converge to market equilibrium, drawing on tools from variational inequalities and Lyapunov stability theory. Key insights include the importance of the dynamical systems perspective to understand how outcomes are reached (beyond just predicting equilibrium), and the finding that while strict Nash equilibria are locally stable, other types of equilibria can lead to complex, non-convergent behavior like cycles.

In a related area, “Multi-Agent Online Control with Adversarial Disturbances” (http://arxiv.org/pdf/2506.18814v1) tackles the challenge of controlling numerous agents in linear dynamical systems facing unpredictable, adversarial disturbances. The authors demonstrate the robustness of gradient-based controllers in this online setting and prove near-optimal sublinear individual regret bounds for each agent, even with minimal communication. Their analysis shows that sharing aggregated control information significantly improves individual regret guarantees, scaling better with the number of agents. This work provides crucial insights for designing robust control strategies in decentralized systems under uncertainty.

Building, Sensing, and Collaborating in Physical Space

Robotics and automation are prime areas for multi-agent systems. “GRAND-SLAM: Local Optimization for Globally Consistent Large-Scale Multi-Agent Gaussian SLAM” (http://arxiv.org/pdf/2506.18885v1) introduces a collaborative Simultaneous Localization and Mapping (SLAM) method utilizing the expressive 3D Gaussian splatting representation for large-scale multi-agent outdoor environments. GRAND-SLAM contributes an implicit tracking module with local optimization over submaps and a robust approach to inter- and intra-robot loop closure integrated into a pose-graph optimization framework. Experiments show superior tracking and rendering quality compared to existing methods on datasets like the Replica indoor dataset and the large-scale Kimera-Multi dataset.

Expanding on multi-agent coordination in robotics, “Safety-Aware Optimal Scheduling for Autonomous Masonry Construction using Collaborative Heterogeneous Aerial Robots” (http://arxiv.org/pdf/2506.18697v1) presents a framework for task planning and scheduling a heterogeneous team of aerial robots (UAVs) for autonomous brick-laying. The framework addresses critical challenges like mortar curing time and safety constraints among simultaneously operating UAVs. It generates construction plans, identifies dependencies, and optimizes task allocation and timing using a mixed-integer programming approach, demonstrating effectiveness in Gazebo simulations.

Further contributing to multi-agent SLAM, “MCN-SLAM: Multi-Agent Collaborative Neural SLAM with Hybrid Implicit Neural Scene Representation” (http://arxiv.org/pdf/2506.18678v1) proposes a distributed framework for collaborative neural SLAM under communication constraints. MCN-SLAM introduces a novel hybrid implicit neural scene representation and techniques for distributed tracking, loop closure, and submap fusion. A significant contribution is the creation of the Dense SLAM (DES) dataset, a real-world large-scale dataset with high-accuracy ground truth for both 3D mesh and continuous-time camera trajectory, addressing a critical gap in existing datasets for neural and Gaussian Splatting-based SLAM. The authors also provide the codebase for MCN-SLAM on GitHub.

Enhancing AI Capabilities with Agents and Advanced Reasoning

Several papers explore the application of agentic principles to improve the capabilities of AI, particularly LLMs. “TRIZ Agents: A Multi-Agent LLM Approach for TRIZ-Based Innovation” (http://arxiv.org/pdf/2506.18783v1) introduces a multi-agent system called TRIZ agents for inventive problem-solving based on the TRIZ methodology. The system simulates a team of specialized LLM agents, each with specific expertise and tool access, collaborating on complex innovation tasks. The paper demonstrates the potential of this decentralized approach to generate diverse, inventive solutions, highlighting the importance of agent specialization and orchestration.

“Understanding Software Engineering Agents: A Study of Thought-Action-Result Trajectories” (http://arxiv.org/pdf/2506.18824v1) provides a large-scale empirical study into the internal workings of LLM-based software engineering agents like RepairAgent, AutoCodeRover, and OpenHands. By analyzing their “thought-action-result” trajectories, the researchers identify behavioral patterns and anti-patterns that distinguish successful from failed executions. This study offers valuable insights for designing more robust and efficient software engineering agents, emphasizing the importance of balancing exploration, explanation, and testing in agent actions. The authors also release their dataset and annotation framework to support future research.

In the domain of generative AI, “Audit & Repair: An Agentic Framework for Consistent Story Visualization in Text-to-Image Diffusion Models” (http://arxiv.org/pdf/2506.18900v1) proposes a collaborative multi-agent framework to address visual inconsistencies in multi-panel story visualizations. The Audit & Repair system uses agents powered by a Vision-Language Model (VLM) to autonomously identify inconsistencies and then apply targeted, localized corrections. This iterative process, which is model-agnostic and compatible with models like Stable Diffusion and Flux, significantly improves character and object consistency across story panels.

Moving towards more structured reasoning, “T-CPDL: A Temporal Causal Probabilistic Description Logic for Developing Logic-RAG Agent” (http://arxiv.org/pdf/2506.18559v1) introduces Temporal Causal Probabilistic Description Logic (T-CPDL). This framework integrates temporal logic, causal modeling, and probabilistic inference into a single Description Logic system. T-CPDL aims to enhance the reasoning capabilities and interpretability of LLMs by providing a structured knowledge representation layer. The authors propose two variants to handle different temporal data granularities and demonstrate improved inference accuracy and confidence calibration on reasoning benchmarks. This work lays the groundwork for advanced Logic-Retrieval-Augmented Generation (Logic-RAG) frameworks.

Another paper focusing on grounding LLMs for specific tasks is “Standard Applicability Judgment and Cross-jurisdictional Reasoning: A RAG-based Framework for Medical Device Compliance” (http://arxiv.org/pdf/2506.18511v1). This research presents a Retrieval-Augmented Generation (RAG) system for automating the determination of regulatory standard applicability for medical devices across different jurisdictions. The system leverages a curated multilingual knowledge base and an LLM to classify standard applicability with traceable justifications and perform cross-jurisdictional reasoning. The authors contribute an international benchmark dataset with expert annotations and demonstrate the system’s effectiveness in identifying relevant standards.

Advancements in Multi-Agent Reinforcement Learning

Multi-Agent Reinforcement Learning (MARL) continues to be a critical area for enabling collaborative agent behaviors. “Transformer World Model for Sample Efficient Multi-Agent Reinforcement Learning” (http://arxiv.org/pdf/2506.18537v1) introduces the Multi-Agent Transformer World Model (MATWM), a novel transformer-based world model for sample-efficient MARL. MATWM combines a decentralized imagination framework, a semi-centralized critic, and a teammate prediction module to handle non-stationarity and partial observability. Evaluated on benchmarks like the StarCraft Multi-Agent Challenge, PettingZoo, and MeltingPot, MATWM achieves state-of-the-art sample efficiency, reaching near-optimal performance with remarkably few environment interactions. The authors have made the codebase available on GitHub.

Building on the concept of behavioral control in MARL, “Dual-level Behavioral Consistency for Inter-group and Intra-group Coordination in Multi-Agent Systems” (http://arxiv.org/pdf/2506.18651v1) proposes Dual-Level Behavioral Consistency (DLBC). This novel MARL control method explicitly regulates agent behaviors at both intra-group and inter-group levels, dynamically modulating behavioral diversity to enhance cooperation and task specialization in multi-agent grouping scenarios. Empirical results show significant performance improvements in various cooperative settings.

Finally, “Multi-Agent Reinforcement Learning for Inverse Design in Photonic Integrated Circuits” (http://arxiv.org/pdf/2506.18627v1) explores the application of MARL to the challenging problem of inverse design for photonic integrated circuits (PICs). By framing the design task as a discrete optimization problem and decomposing the design space into thousands of individual agents, the authors develop two MARL algorithms, Bandit Actor-Critic (BAC) and Bandit Proximal Policy Optimization (BPPO). These algorithms outperform traditional gradient-based optimization in sample efficiency and performance on 2D and 3D PIC design tasks, with the reinforcement learning environment and algorithms made open-source on GitHub.

Exploring the Boundaries of Causality and Fairness

Venturing into the theoretical realm, “Unilateral determination of causal order in a cyclic process” (http://arxiv.org/pdf/2506.18540v1) explores the fascinating possibility of cyclic causal orders. The paper introduces a novel process where a single agent can unilaterally determine their causal ordering with respect to others, a concept beyond traditional multilateral determination. This ground-breaking work is certified through a newly defined causal game and the violation of a causal inequality, pushing the boundaries of our understanding of causal structures.

In economics and computer science, “Fair Allocation with Money: What is Your Objective?” (http://arxiv.org/pdf/2506.18794v1) examines different objectives for achieving fair allocation of indivisible items when monetary transfers are involved. The paper compares models like balanced payments, subsidies, and charging positive amounts, analyzing the theoretical relationships between upper and lower bounds for various optimization goals. A key insight is that bounding the maximum subsidy per agent is a “stronger” objective, implying bounds for others.

Understanding and Steering LLMs

Beyond using LLMs within agents, researchers are also studying the behavior of populations of LLMs. “Reply to ‘Emergent LLM behaviors are observationally equivalent to data leakage’” (http://arxiv.org/pdf/2506.18600v1) responds to a critique suggesting that emergent behaviors in LLM populations are merely due to data leakage. The authors defend their previous work on social conventions and collective bias, arguing these dynamics cannot be fully explained by data contamination or simple optimal strategy reproduction, highlighting the emergent, context-sensitive nature of LLM behavior in multi-agent settings.

Finally, “Steering Conceptual Bias via Transformer Latent-Subspace Activation” (http://arxiv.org/pdf/2506.18887v1) investigates methods to steer the output of transformer-based LLMs, specifically focusing on biasing scientific code generation towards a target language like C++. The paper proposes a gradient-refined adaptive activation steering framework (G-ACT) that trains lightweight per-layer probes to reliably steer the model’s output. This approach offers a scalable, interpretable, and efficient mechanism for concept-level control in LLMs, with the potential for ensuring reproducible model behavior.

Modeling Dynamic Biological Processes

Moving into the biomedical domain, “Temporal Neural Cellular Automata: Application to modeling of contrast enhancement in breast MRI” (http://arxiv.org/pdf/2506.18720v1) introduces TeNCA (Temporal Neural Cellular Automata), a novel approach for modeling dynamic contrast enhancement in breast MRI. TeNCA extends traditional Neural Cellular Automata to handle temporally sparse and non-uniformly sampled data, leading to physiologically plausible temporal evolution of contrast enhancement. Evaluated on diverse breast MRI datasets like MAMA-MIA and Duke-Breast-Cancer-MRI, TeNCA demonstrates superior performance in generating images that align with ground truth sequences, while requiring fewer parameters than existing methods. The authors also provide the code for TeNCA on GitHub.
