WebMar 24, 2024 · A complete graph is a graph in which each pair of graph vertices is connected by an edge. The complete graph with n graph vertices is denoted K_n and has (n; 2)=n(n-1)/2 (the triangular numbers) undirected edges, where (n; k) is a binomial coefficient. In older literature, complete graphs are sometimes called universal graphs. … Webgraph: [noun] the collection of all points whose coordinates satisfy a given relation (such as a function).

In the mathematical field of graph theory, a path graph or linear graph is a graph whose vertices can be listed in the order v1, v2, …, vn such that the edges are {vi, vi+1} where i = 1, 2, …, n − 1. Equivalently, a path with at least two vertices is connected and has two terminal vertices (vertices that have degree 1), while all others (if any) have degree 2. WebIn this paper, we consider the time averaged distribution of discrete time quantum walks on the glued trees. In order to analyze the walks on the glued trees, we consider a reduction to the walks on path graphs.

WebIn graph theory, an Eulerian trail (or Eulerian path) is a trail in a finite graph that visits every edge exactly once (allowing for revisiting vertices). Similarly, an Eulerian circuit or Eulerian cycle is an Eulerian trail that starts and ends on the same vertex. WebThe hamiltonian graph is the graph having a Hamiltonian path in it i.e. a path that visits each and every vertex of the graph exactly once, such graphs are very important to study because of their wide applications in real-world problems. Hamiltonian graphs are used for finding optimal paths, Computer Graphics, and many more fields.
