A fast algorithm for minimum weight odd circuits and cuts in planar graphs

چکیده
We give a simple O(n3/2 log n) algorithm for finding a minimum weight odd circuit in planar graphs. By geometric duality, the same algorithm can be used to find minimum weight odd cuts. For general sparse graphs, the fastest known algorithms for these two problems take O(n2 log n) time and O(n3 log n) time, respectively. © 2004 Elsevier B.V. All rights reserved.

A Simple MAX-CUT Algorithm for Planar Graphs
The max-cut problem asks for partitioning the nodes V of a graph G = (V,E) into two sets (one of which might be empty), such that the sum of weights of edges joining nodes in different partitions is maximum. Whereas for general instances the max-cut problem is NPhard, it is polynomially solvable for certain classes of graphs. For planar graphs, there exist several polynomial-time methods determ...
متن کاملContiguous Minimum Single-Source-Multi-Sink Cuts in Weighted Planar Graphs
We present a fast algorithm for uniform sampling of contiguous minimum cuts separating a source vertex from a set of sink vertices in a weighted undirected planar graph with n vertices embedded in the plane. The algorithm takes O(n) time per sample, after an initial O(n) preprocessing time during which the algorithm computes the number of all such contiguous minimum cuts. Contiguous cuts (that ...
متن کاملOn Odd Cuts and Plane Multicommodity
Let T be an even subset of the vertices of a graph G. A T-cut is an edge-cutset of the graph which divides T into two odd sets. We prove that if G is bipartite, then the maximum number of disjoint !T-cuts is equal to the minimum cardinality of a set of edges which meets every T-cut. (A weaker form of this was proved by Edmonds and Johnson.) We deduce a solution to the real-valued multi-commodit...
متن کاملCuts in Directed Planar Networks by Parallel C Omput at Ions
We reduce the exponent to 3 in the case when the network is embedded in the plane beforehand and to 4 otherwise. The reader is supposed to be familiar with graphs, planar graphs, multigraphs and so on (see [1]). We use the well-known method in a similar way as in [4] which consists in the fact that the problem of finding minimum cuts in a network can be reduced to the shortest path problem in i...

We consider the maximum integral tWo-Commodity flow problem in augmented planar graphs (i.e., with both source-sink edges added) and provide an o(IVI 2 1ogIVI) algorithm for that problem. Let G = (V, E) be a graph and w : E-t Z+ a weight function. Let T C V be an even subset of the vertices of G. A T-cut is an edge-cutset of the graph which divides T into two odd sets. Lomonosov gave a good cha...
