However, they appear quite frequently as minor closed graph classes. For example, series-parallel graphs (\(Ex(K_4)\)) or outerplanar graphs (\(Ex(K_4,K_{2,3})\)) are sub-critical and in general it is conjectured that a minor closed graph class is sub-critial if at least one of the excluded minors is planar.

Introduction to Combinatorial Optimization. Point-based methods undertaken by experienced human operators are very effective for traditional photogrammetric activities, but they are not appropriate in the autonomous environment of digital photogrammetry. To develop more reliable and accurate techniques, higher level objects with linear features accommodating elements other than points are alternatively adopted for Cited by: 8.

This result can be used to show that for every 2-connected graph, there is a family of at most c' circuit which cover each edge of the graph at least twice. This settles a question posed by Oxley. We prove the dual of the above result namely, for any k-connected graph having largest circuit of length c >= 2k, there is a bond which intersects.

(3) (Berg and Jordán [6]) There exists a function h(k) such that for integers k ≥ 1 and n ≥ h(k), every strongly k-arc-connected n-vertex digraph contains a strongly k-arc-connected spanning.

This paper solves the problem of determining the least number of arcs required in a k-arc-connected graph on n nodes by describing constructions that. An efficient heuristic is presented for the problem of finding a minimum-size k-connected spanning subgraph of an (undirected or directed) simple graph G=(V,E).There are four versions of the problem, and the approximation guarantees are as follows:minimum-size k-node connected spanning subgraph of an undirected graph 1 + [1/k], minimum-size k-node Cited by: I'm reading the book Graphs and Their Uses which contains the following theorem and proof: THEOREM A connected graph with 2k odd vertices contains a family of k distinct trails which, together, traverse all edges of the graph exactly once.

Nash-Williams' Theorem directly implies that an undirected graph G has a k-arc-connected orientation iff G is 2k-edge-connected [4, 12]. After then, a k -arc-connected orientation of a 2 k -edge-connected undirected graph G can be found in polynomial time based upon the complexity of the Edmonds-Giles Problem [ 4, 13, 14 ].Author: William Chung-Kung Yen.

Other readers will always be. A minimal edge cover is an edge cover that is minimal with respect to inclusion. The edge cover number is the size of a minimum cardinality edge cover of G and it is usually denoted by β ′ (G).

Proposition 1. Given a graph G = (V, E), finding a maximum cardinality star partition is equivalent to finding a minimum cardinality edge cover. ProofAuthor: G.

Step 1: Building the input graph. The input for the throughput algorithm is a “minimal” graph built by adding arcs to the original HSDFG based on the current state of the model. More precisely, an arc is assumed to exist between actors i and j iff A R C i j = 1; unbound A R C variables are therefore treated as if they were set to by: 4.

This paper explores new approaches to the symmetric traveling-salesman problem in which 1-trees, which are a slight variant of spanning trees, play an essential role. A 1-tree is a tree together with an additional vertex connected to the tree by two by: Connected graph searching in chordal graphs.

If G has a vertex s of degree at least 4 then it follows from a result of from IT at King Abdulaziz University. Throughout the book, there is a strong focus on applications which include quantum mechanics, bioinformatics, embedded computing, and the travelling salesman problem.

Detailed indices and topic-oriented chapters ease navigation, and more than exercises, figures and open problems are included to help immerse the reader in all aspects. Arc-Disjoint Strong Spanning Subgraphs of K-Arc-Strong Tournaments.

Joint work with Jorgen Bang-Jensen. A tournament, is an orientation of a complete graph. k-arc-strong means that the digraph is strong (i.e. there is an (x,y)-path and a (y,x)-path for all distinct vertices x and y) whenever we delete at most k-1 arcs.

Let G(V, E) be an undirected connected graph, where each vertex v is associated with a positive cost C(v) and each edge e (u, v) is associated with two positive weights, W(u v) and W(v u). We consider a new graph problem, called the edge-orientation problem (the EOP).

The major issue is to assign each edge e (u, v) an orientation, either from u to v, denoted as u. Show that: a) each of the graphs P4 and C5 (shown in Figure ) is self-complementary, b) every self-complementary graph is connected, c) if G is self-complementary, then n ≡ 0, 1 (mod 4), d) every self-complementary graph on 4k + 1 vertices has a vertex of degree 2k.
