human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "ht ring paxos theory of high throughput state machine replication for clustered data centers"):
  Abstract: Implementations of state-machine replication (SMR) prevalently use the variants of Paxos. Some of the recent variants of Paxos like, Ring Paxos, Multi-Ring Paxos, S-Paxos and HT-Paxos achieve significantly high throughput. However, to meet the growing demand of high throughput, we are proposing HT-Ring Paxos, a variant of Paxos that is basically derived from the classical Paxos. Moreover, it also adopts some fundamental concepts of Ring Paxos, S-Paxos and HT-Paxos for increasing throughput. Furthermore, HT-Ring Paxos is best suitable for clustered data centers and achieves comparatively high throughput among all variants of Paxos. However, similar to Ring Paxos, latency of the HT-Ring Paxos is quite high as compared with other variants of Paxos.
