Abstract:
The problem of maximization of the number of nodes for a fixed degree and diameter for circulant networks is considered. The known lower bound for the maximum order of quadruple circulant networks is improved by $O(\frac32d^3)$ for any odd diameter $d>1$. A family of circulant networks is found at which the obtained estimate is attained. Tabl. 1, bibl. 7.
Keywords:circulant networks, diameter, the maximum order of a graph.
