摘      要：

       In a centralized system, all processing and decision-making is handled by a single entity, which can become a bottleneck as the system grows in size and complexity. Decentralized algorithms distribute the processing load across multiple nodes, allowing the system to scale much more effectively. Many decentralized algorithms distribute the global objective function across multiple nodes such that each node only handle its own local objective function.
