WebPartitioning into two connected graphs. For the example graph in the introductory section, the Fiedler vector is . The negative values are associated with the poorly connected vertex 6, and the neighbouring articulation point, vertex 4; while the positive values are associated with the other vertices. http://orion.towson.edu/~mzimand/athcomp/List_of_NP-complete_problems.pdf

WebIn the mathematical field of graph theory, a bipartite graph (or bigraph) is a graph whose vertices can be divided into two disjoint and independent sets and , that is every edge … In mathematics, a graph partition is the reduction of a graph to a smaller graph by partitioning its set of nodes into mutually exclusive groups. Edges of the original graph that cross between the groups will produce edges in the partitioned graph. If the number of resulting edges is small compared to the original … See more Typically, graph partition problems fall under the category of NP-hard problems.

"Weba graph partitioning algorithm to partition the graph. That partitioning gives a clustering of the original data points. Intuitively, this will give us the right cluster showing on the right; even though there are points which are very far in the same cluster it is possible to go from any point in a cluster to any other point in " - Graph partition wiki
