# Application of graph theory in domination of graphs

In this paper we prove that if the degree condition is replaced by d x d y n 2k 1 for a given natural number k then Gcontains kedge disjoint Hamiltonian Cycles. A loop is just an edge that joins a node to itself so a Hamiltonian cycle is a path traveling from a point back to itself visiting every node en route. The difference grows with the size of the graphs because searching for elementary cycle is an elementary path where the initial and final vertex coincide. Then we can describe the Hamiltonian circuits in terms of the quot moves quot a and b and their inverses a 39 and b Give an argument that the resulting graph is 3-colorable if and only if the input 3SAT in- stance is satisfiable.

## Dominating set

New York: McGraw-Hill. Graph-theoretic methods, in various forms, have proven particularly useful in linguistics , since natural language often lends itself well to discrete structure. A simpler proof considering only configurations was given twenty years later by Robertson , Seymour , Sanders and Thomas. The use of diagrams of dots and lines to represent graphs actually grew out of 19th-century chemistry , where lettered vertices denoted individual atoms and connecting lines denoted chemical bonds with degree corresponding to valence , in which planarity had important chemical consequences. Another class of graphs is the collection of the complete bipartite graphs K m , n , which consist of the simple graphs that can be partitioned into two independent sets of m and n vertices such that there are no edges between vertices within each set and every vertex in one set is connected by an edge to every vertex in the other set. It also helps us to show the bond relation in between atoms and molecules, also help in comparing structure of one molecule to other.

### Dominating set - Wikipedia

Retrieved 27 May Still another such problem, the minor containment problem, is to find a fixed graph as a minor of a given graph. A path may follow a single edge directly between two vertices, or it may follow multiple edges through multiple vertices. The development of algorithms to handle graphs is therefore of major interest in computer science.

## Applications of Graph Theory

Description: For instance, the vertices of the simple graph shown in the diagram all have a degree of 2, whereas the vertices of the complete graph shown are all of degree 3.

There exist a pair of polynomial-time L-reductions between the minimum dominating set problem and the set cover problem. History at your fingertips.
