All-to-all Routing on Kautz Graphs: Regular Routing Beats Shortest Paths

Vance Faber, Noah Streib

We study packet routing in the Kautz digraph K(d,D), where every ordered pair of distinct vertices is connected by a unique shortest directed path. The regular routing introduced i…

Algebraic Constructions for the Digraph Routing Problems

Nyumbu Chishwashwa, Vance Faber, Noah Streib

Efficiency of routing on a regular digraph often involves finding opitmal properties of the graph. For example, the diameter of a digraph is the maximum distance between any two ve…

Network Routing on Regular Digraphs and Their Line Graphs

Vance Faber, Noah Streib

This paper concerns all-to-all network routing on regular digraphs. In previous work we focused on efficient routing in highly symmetric digraphs with low diameter for fixed degree…

All-to-all Routing on Digraph Networks

Nyumbu Chishwashwa, Vance Faber, Noah Streib

We discuss an open problem and its converse first posed by Dougherty and Faber in [3], "Network routing on regular directed graphs from spanning factorizations." Does every vertex…

Dimension of posets with planar cover graphs excluding two long incomparable chains

David M. Howard, Noah Streib, William T. Trotter +2

It has been known for more than 40 years that there are posets with planar cover graphs and arbitrarily large dimension. Recently, Streib and Trotter proved that such posets must h…

Hypergraph Versals

Vance Faber, Noah Streib

Let H be a hypergraph on n vertices with the property that no edge contains another. We prove some results for a special case of the Isolation Lemma when the label set for the edge…
