Description: A quorum graph is a type of graph used in distributed computing to represent the relationships between nodes that can reach a consensus. In this context, the nodes represent entities that must collaborate to make decisions or perform operations in a coordinated manner. The structure of the graph allows for visualizing how these nodes are connected and how they can communicate with each other to achieve agreement. Each node in the graph may have a set of connections that represent possible interactions with other nodes, and the quorum refers to the minimum number of nodes that must agree for a decision to be valid. This feature is crucial in distributed systems, where communication can be intermittent and reliability is essential. Quorum graphs are fundamental to ensuring that decisions are made efficiently and that the system maintains its integrity, even in the presence of failures or desynchronization among nodes. Additionally, these graphs can be used to model different consensus algorithms, such as the Paxos or Raft algorithms, which are widely used in distributed systems and cluster management. In summary, quorum graphs are a theoretical and practical tool that allows for understanding and designing robust and efficient distributed systems.
