Given the linkage di erence in Figure 2, we see that quite a few nodes far away from the cut point have wrong signs, that is, they belong to the other ....

....by using the third and fourth smallest eigenpairs of the graph Laplacian. Spielman and Teng [29] present an upper bound on the Fiedler value of bounded degree d dimensional graphs, and they relate this upper bound to the number of edges cut by a Fiedler cut. In contrast, Guattery and Miller [14] present graphs for which spectral partitioning yields poor separators. Simon and Teng [28] show that p way partitions produced by recursive bisection can yield far from optimal partitions, even when an optimal partitioning algorithm is used. Computing the Fiedler vector can be time consuming. ....

....has shown how finding a partition of a graph which minimizes the number of edges cut can be transformed into an eigenvalue problem involving the graph Laplacian. This is the foundation of spectral methods. Theory exists to show the effectiveness of this approach. The work of Guattery and Miller [7] present examples of graphs for which spectral partitioning does not work well. Nevertheless, spectral partition methods work well on boundeddegree planar graphs and finite element meshes [17] Chan et al. 3] show that spectral partitioning is optimal in the sense that the partition vector ....
