    Research on the diameter of bidirectional double-loop networks G(N;±1,±s) in cartesian coordinates by LIU Hui, FANG Mu-yun, ZHENG Xiao, HANG Ting-ting

    Published 2011-01-01
    “…A new method to research the diameter of the bidirectional double-loop networks G(N;±1,±s) was presented based on cartesian coordinates.Using this method,the limited bound of diameter of the bidirectional double-loop net-works G(N;±1,±s) presented by Boesch and Wang was certified and the limited bound of average diameter was given.At last,the simulation of the graph of bidirectional double-loop networks G(N;±1,±s) for any given N,s was given.Com-pared whith L-shaped tile simulation which can not be used in the bidirectional double-loop networks directly,this method improved the research level of the bidirectional double-loop networks greatly.…”
