WebAnswer: Yes; an Eulerian path visits each edge exactly once, but it can visit a vertex as many times as is needed. The number of visits to a node is half that node’s degree for an Eulerian circuit. For a path where start and end nodes differ, those nodes could be of odd degree and have an extra ... WebA path is a type of open walk where neither edges nor vertices are allowed to repeat. There is a possibility that only the starting vertex and ending vertex are the same in a path. In an open walk, the length of the walk must be more than 0. So for a path, the following two points are important, which are described as follows: Edges cannot be ...
