WebAs it is a directed graph, each edge bears an arrow mark that shows its direction. 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. WebNext we have a similar graph, though this time it is undirected. Figure 2 gives the pictorial view. Self loops are not allowed in undirected graphs.

WebOct 8, 2012 · Relaxing an edge, (a concept you can find in other shortest-path algorithms as well) is trying to lower the cost of getting to a vertex by using another vertex. You are calculating the distances from a beginning vertex, say S, to all the other vertices. At some point, you have intermediate results -- current estimates.
