Magic Graphs
Alison M. Marr,Walter D. Wallis +1 more
TL;DR: The second edition of as discussed by the authors contains a new chapter on magic labeling of directed graphs and interesting counting arguments new research problems and exercises covering a range of difficulties a fully updated bibliography and index This concise, selfcontained exposition is unique in its focus on the theory of magic graphs/labelings.
Vertex-Magic Total Labelings of Graphs
TL;DR: A vertex-magic total labeling of a graph with vertices and edges is defined as a one-to-one map taking the nodes and edges onto the integers $1, 2,..., v+e$ with the property that the sum of the label on a vertex and the labels on its incident edges is a constant independent of the choice of vertex.

Detection of abnormal change in a time series of graphs
TL;DR: In the management of large enterprise communication networks, it becomes difficult to detect and identify causes of abnormal change in traffic distributions when the underlying logical topology is unknown.

Edge-Magic Total Labelings
Alison Marr,Walter D. Wallis +1 more
TL;DR: An edge-magic total labeling on a graph G is a one-to-one map λ from V (G) \ cup E(G) onto the integers 1,2, …, v + e, where wt(xy) = k for any choice of edge xy.
