human: Given a node-centered hypergraph: <hypergraph>, where nodes represent papers and hyperedges represent groups of papers sharing a common citing paper.

Details of the hypergraph:
Center node: "ICSIM: An Object Oriented Simulation Environment for Structured Connectionist Nets. Class Project Report, Physics 250"
  Abstract: ICSIM is a simulator for structured connectionism under development at ICSI. Structured connectionism is characterized by the need for flexibility, efficiency and support for the design and reuse of modular substructure. We take the position that a fast object-oriented language like Sather [5] is an appropriate implementation medium to achieve these goals. The core of ICSIM consists of a hierarchy of classes that correspond to simulation entities. New connectionist models are realized by combining and specializing pre-existing classes. Whenever possible, auxillary functionality has been separated out into functional modules in order to keep the basic hierarchy as clean and simple as possible.

Connected through hyperedge HE-1 (induced by source paper "ICSIM: An Object-Oriented Connectionist Simulator gives an overview of the simulator. Its main concepts, the"):
