Web6. Select the unvisited vertex that is marked with the smallest tentative distance, and set it as the new current vertex. Repeat steps 3-6 until all vertices have been visited. Here are the steps of each iteration: 1. Start at vertex F with a distance of 0. 2. Move to vertex E with a distance of 3. 3. Move to vertex B with a distance of 5. 4. WebPath is an open walk with no repetition of vertices and edges. If you make a trail (or path) closed by coinciding the terminal vertices, then what you end up with is called a circuit (or cycle). Circuit is a closed walk where vertices can repeat, but not edges. Cycle is a closed walk where neither vertices nor edges can repeat. But since it is ...

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 ...
