We can use this fact to find the graph diameter by computing log n values of A k. Here's how the algorithm works: let A be the adjacency matrix of the graph with an added self loop for each node. Set M 0 = A. While M k contains at least one zero, compute M k+1 = M k2. WebApr 5, 2013 at 8:36. 1. It is actually not bounded by n/k. Take for example the following 3-regular graph: start with one vertex adjacent to all the vertices of a path on 3 vertices. Join the two extremity to an other vertex, says u. do a copy of this graph with v the copy of u and join u and v. This graph has diameter 5, 10 vertices and degree 3. trump and jesus billboard

WebExamples of using a straight line graph to find a formula. Example 1: To show that πR 2 gives the area of a circle. For any circle π is the number 3.14 in the equation: circumference = 2π x radius or π x diameter. So π is circumference diameter. Starting from that (as a definition of π) we can show that the area of a circle is πR 2. WebIn the mathematical field of graph theory, a path graph (or linear graph) is a graph whose vertices can be listed in the order v 1, v 2, …, v n such that the edges are {v i, v i+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.

WebSince your graph has radius 1 there must be a central vertex v to which all other vertices are connected. Therefore the underlying backbone of your graph family are the star graphs S n (with n + 1 total vertices). Clearly we require n > 1.

For the complete bipartite graph K m, n, you need two steps to reach any vertex so the radius and the diameter are both 2. The exception to this is when m or n is 1. In that case, the single vertex can reach any other vertex in a single step so the radius is reduced to 1. philippine embassy nbi clearanceWebA polar equation describes a curve on the polar grid.
