Graph Coloring as a Measure of Network Vulnerability

Mia Destefano, Grace Mulry, Mason Nakamura +2

We consider new parameters for conditional network vulnerability related to graph coloring. We define a network to be in operation if the chromatic number (or index) is greater tha…

Clumsy Packing of Polyominoes in Finite Space

Emma Miller, Mitchel O'Connor, Nathan Shank

Clumsy packing is considered an inefficient packing, meaning we find the minimum number of objects we can pack into a space so that we can not pack any more object. Thus we are eff…

Vertex and Mixed -Diameter Component Connectivity

Adam Buzzard, Nathan Shank

n the -diameter component connectivity model a network is consider operational if there is a component with diameter at least . Therefore, a network is in a failure state if…

On proportional network connectivity

Ashley Armbruster, Jieqi Di, Nicholas Hanson +1

The reliability of a network is an important parameter to consider when building a network. Different characteristics of the network can become unreliable over time or from other o…

Partisan Combinatorial Game of Edge and Vertex Removal on Graphs

Nathan Shank, Devon Vukovich

We consider three variants of a partisan combinatorial game between two players, Left and Right, played on an undirected simple graph. Left is able to delete vertices (and incident…

Extremal Problems Related to the Cardinality Redundance of Graphs

Daniel McGinnis, Nathan Shank

A dominating set of a graph is a set of vertices such that for all , either or for some . The cardinality redundance of a ve…
