Abstract

Undirected double-loop networks G(n; ± s1, ± s2), where n is the number of its nodes, s1 and s2 are its steps, 1≤s1s2n / 2 and gcd(n, s1, s2)=1, are important interconnection networks. In this paper, by using the four parameters of the L-shape tile and a solution (x̄,ȳ) of a congruence equation s1x+s2y≡1 (modn), we give a constant time optimal routing algorithm for G(n; ± s1, ± s2).
