Although simple route planning is not as daunting as TSP, there are some similarities, in that it involves a weighted, undirected graph, requiring the algorithm to take into account the cost of ...

The Annals of Statistics, Vol. 26, No. 4 (Aug., 1998), pp. 1434-1495 (62 pages) A chain graph (CG) is a graph admitting both directed and undirected edges with (partially) directed cycles forbidden.

Each pixel in the image has 2 types of undirected edges - n − links n-links n −links, representing neighborhood linkage, and t − link t-link t− link, representing linkages to each terminal. Assuming ...

In directed graphs, relationships are asymmetric and these asymmetries contain essential structural information about the graph. Directed relationships lead to a new type of clustering that is not ...
