Center node: "a family of three weight binary linear codes"
  Abstract: In this paper, a family of three-weight binary linear codes is constructed. Some of the linear codes obtained are either optimal or almost optimal. These codes have applications in association schemes, authentication codes, and secret sharing schemes, in addition to their usages in consumer electronics, communication and data storage systems.

Connected through hyperedge HE-1 (induced by source paper "a class of three weight and five weight linear codes"):
  with members:
    - "linear codes from some 2 designs"
    - "linear codes with two or three weights from quadratic bent functions"
    - "a class of two weight and three weight codes and their applications in secret sharing"
    - "a class of three weight cyclic codes"
    - "five families of three weight ternary cyclic codes and their duals"
    - "hamming weights in irreducible cyclic codes"

Question: Please tell me which class the center node belongs to. The 40 classes are: cs.NA(Numerical Analysis), cs.MM(Multimedia), cs.LO(Logic in Computer Science), cs.CY(Computers and Society), cs.CR(Cryptography and Security), cs.DC(Distributed, Parallel, and Cluster Computing), cs.HC(Human-Computer Interaction), cs.CE(Computational Engineering, Finance, and Science), cs.NI(Networking and Internet Architecture), cs.CC(Computational Complexity), cs.AI(Artificial Intelligence), cs.MA(Multiagent Systems), cs.GL(General Literature), cs.NE(Neural and Evolutionary Computing), cs.SC(Symbolic Computation), cs.AR(Hardware Architecture), cs.CV(Computer Vision and Pattern Recognition), cs.GR(Graphics), cs.ET(Emerging Technologies), cs.SY(Systems and Control), cs.CG(Computational Geometry), cs.OH(Other Computer Science), cs.PL(Programming Languages), cs.SE(Software Engineering), cs.LG(Machine Learning), cs.SD(Sound), cs.SI(Social and Information Networks), cs.RO(Robotics), cs.IT(Information Theory), cs.PF(Performance), cs.CL(Computation and Language), cs.IR(Information Retrieval), cs.MS(Mathematical Software), cs.FL(Formal Languages and Automata Theory), cs.DS(Data Structures and Algorithms), cs.OS(Operating Systems), cs.GT(Computer Science and Game Theory), cs.DB(Databases), cs.DL(Digital Libraries), cs.DM(Discrete Mathematics). Directly output the class name.
