May 11, 2021 · 1. One way of finding an Euler path: if you have two vertices of odd degree, join them, and then delete the extra edge at the end. That way you have all vertices of even degree, and your path will be a circuit. If your path doesn't include all the edges, take an unused edge from a used vertex and continue adding unused edges until you get a ... Hamiltonian Path - An Hamiltonian path is path in which each vertex is traversed exactly once. If you have ever confusion remember E - Euler E - Edge. Euler path is a graph using every edge (NOTE) of the graph exactly once. Euler circuit is a euler path that returns to it starting point after covering all edges.
