WebTake the statement "A graph has n vertices that are pairwise X", where X can be anything. In your example, X is 'adjacent'. The term "pairwise" means that every possible pair of those n vertices satisfies X. Applying this to your example, it means that each pair of those 8 vertices are adjacent. You correctly concluded that the result is a ...

They are: A graph is a picture of dots called vertices and lines called edges. An edge that starts and ends at the same vertex is … WebNode 0 has three adjacent nodes - 0, 1, 2, meaning that graph has edges 0-0, 0-1, and 0-2. The weight of those edges can also be read from the adjacency list. The weight of edge 0-0 is 25, the weight of edge 0-1 is 5, and so on, for every edge in the graph.

Note that in a directed graph, ‘ab’ is different from ‘ba’. Simple Graph. A graph with no loops and no parallel edges is called a simple graph. The maximum number of edges possible in a single graph with ‘n’ vertices is n C 2 where n C 2 = n(n – 1)/2. greenock east scotland

"WebGraph Theory Definitions. Graph. A collection of vertices, some of which are connected by edges. More precisely, a pair of sets \(V\) and \(E\) where \(V\) is a set of vertices and \(E\) is a set of 2-element subsets of \(V\text{.}\) Adjacent. Two vertices are adjacent if they are connected by an edge. Two edges are adjacent if they share a vertex. " - Graph theory adjacent edges
