New formulations of the Hop-Constrained Minimum Spanning Tree problem via Miller–Tucker–Zemlin constraints

Abstract: a b s t r a c tGiven an undirected network with positive edge costs and a natural number p, the Hop-Constrained Minimum Spanning Tree problem (HMST) is the problem of finding a spanning tree with minimum total cost such that each path starting from a specified root node has no more than p hops (edges). In this paper, we develop new formulations for HMST. The formulations are based on Miller-Tucker-Zemlin (MTZ) subtour elimination constraints, MTZ-based liftings in the literature offered for HMST, and a new set… Show more

“…We refer the reader to [21,23] for a literature review on the HMST (e.g. [1,9,[15][16][17]) and related problems. See also the works of [27] and [28] proposing ACO approaches to problems in communication networks which, although related, are different since neither arc flows nor flow requirements are considered.…”

“…These constraints are required, especially in some transportation and networking design problems, where a particular node (depot) is the starting and the ending point for any tour. In other words, any tour which doesn't contain the depot is eliminated([26], [18], [1], [3], [2], and [13] ). Consequently, any new formulation containing "Miller-Tucker-Zemlin constraints" is referred to as MTZ formulation.…”

“…This kind of lifting has been used to model the hop‐constrained MST (Gouveia, ; Akgün and Tansel, ). In such a case, however, n(G) in is reduced by a fixed value p , which represents the maximum number p of hops from the root allowed in the solution.…”
