Dijkstra's algorithm ( / ˈdaɪkstrəz / DYKE-strəz) is an algorithm for finding the shortest paths between nodes in a weighted graph, which may represent, for example, road networks. It was conceived by computer scientist Edsger W. Dijkstra in 1956 and published three years later. [4] [5] [6] Expert Answer. Use the Sorted Edges Algorithm (also known as Cheapest Link Algorithm) to find a minimum weight Hamiltonian circuit. For every step of the algorithm, state every edge you consider (by weight) and whether you include it. If you do not include it, explain why in terms of the algorithm. (You do not need to create a drawing to submit).The results obtained are that routes created using the Cheapest Link Algorithm have an average efficiency of 66.86% better than other Hamilton circuits formed on the same graph. </p.Using a different algorithm, such as the cheapest-link algorithm, or even just starting at a different city with the nearest-neighbor algorithm, may produce a different and possibly shorter tour. If we start at Allentown and use the nearest-neighbor algorithm, the tour produced is Allentown– Reading–Philadelphia–Scranton–Pittsburgh–Erie–Allentown, for …Finding the cheapest path to all nodes includes finding the cheapest path to the other node in the pair. But isn't Dijkstra's algorithm overkill if we only care about one pair of nodes? Actually no, because we'll still need to consider other nodes in the graph to make sure we've found the lowest-cost weighted path.

The positive aspect of the brute-force algorithm is that it is an optimal algorithm. (An optimal algorithm is an algorithm that, when correctly implemented, is guaranteed to produce an optimal solution.) In the case of the brute-force algorithm, we know we are getting an optimal solution because we are choosing from among all possible tours.

2-Opt is a local search tour improvement algorithm proposed by Croes in 1958 [3]. It originates from the idea that tours with edges that cross over aren’t optimal. 2-opt will consider every possible 2-edge swap, swapping 2 edges when it results in an improved tour. 2-Opt. 2-opt takes O (n^2) time per iteration.
