Abstract

Let G = G(n,m) be a rectangular solid grid graph and A(G) be a minimum length Eulerian augmentation of G. Let l0, . . . , lt ∈ N such that Σt i=0 li = |E(A(G)|, where 2(n + m) ≤ li = 2ki. In this paper, we exhibit a constructive procedure providing an edge-disjoint decomposition of A(G) into closed trails T0, . . . , Tt such that |E(Ti)| = li.
