Web1 de ago. de 2024 · This algorithm is guaranteed to return a cut that is smaller or equal to the one returned by the classic spectral bisection. To this end, we investigate combinatorial properties of certain configurations of a graph partition. These properties, that we call organized partition s, are shown to be related to the minimality and maximality of a cut. WebThis work presents a new method for symmetrization of directed graphs that constructs an undirected graph with equivalent pairwise effective resistances as a given directed graph. Consequently a graph metric, square root of effective resistance, is preserved between the directed graph and its symmetrized version. slugging through
