Multi-agent systems (MAS) are becoming increasingly prevalent across various industries due to their ability to enhance efficiency, adaptability, and collaborative intelligence through decentralized and autonomous agents. In clinical trial recruitment, they streamline processes by matching patients with trials and optimizing site selection, while in financial portfolio management, they aid in tasks like fraud detection and personalized investment strategies. For policy simulation, MAS facilitate stakeholder negotiation and resource allocation, and in energy trading, they enable autonomous coordination of distributed resources. These systems also optimize supply chain operations by dynamically adjusting to disruptions and demand fluctuations. Despite their benefits, challenges such as complexity, coordination, conflict resolution, and security concerns must be addressed to maximize their potential. Looking ahead, MAS are expected to increasingly collaborate with human teams, optimize logistics, and be deployed in smart cities, offering transformative solutions for complex global challenges while maintaining human oversight.
