Follow edges one at a time.Degree of node A. ○ The number of edges that include A. ○ Strongly Connected Component. ○ A set of nodes where there is an path between any two nodes in ...The definition of Euler path in the link is, however, wrong - the definition of Euler path is that it's a trail, not a path, which visits every edge exactly once. And in the definition of trail, we allow the vertices to repeat, so, in fact, every Euler circuit is also an Euler path.Step 2: Remove an edge between the vertex and any adjacent vertex that is NOT a bridge, unless there is no other choice, making a note of the edge you removed. Repeat this step until all edges are removed. Step 3: Write out the Euler trail using the sequence of vertices and edges that you found.A directed path in a digraph is a sequence of vertices in which there is a (directed) edge pointing from each vertex in the sequence to its successor in the sequence, with no repeated edges. A directed path is simple if it has no repeated vertices.
