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 "optimal scalar linear index codes for some symmetric multiple unicast problems"):
  Abstract: The capacity of symmetric instance of the multiple unicast index coding problem with neighboring antidotes (side-information) with number of messages equal to the number of receivers was given by Maleki, Cadambe and Jafar. In this paper we consider ten symmetric multiple unicast problems with lesser antidotes than considered by them and explicitly construct scalar linear codes for these problems. These codes are shown to achieve the capacity or equivalently these codes shown to be of optimal length. Also, the constructed codes enable the receivers use small number of transmissions to decode their wanted messages which is important to have the probability of message error reduced in a noisy broadcast channel. Some of the cases considered are shown to be critical index coding problems and these codes help to identify some of the subclasses considered by others to be not critical index coding problems.
