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. can i afford a second investment property
