Pick the next cheapest uncolourededge unless: your new edge closes a smaller circuit your new edge results in three colourededges coming out of a single vertex. at your will. Repeat Step 2 until the hamilton circuit is complete.

We will look at three greedy, approximate algorithms to handle the Traveling Salesman Problem. The Nearest-Neighbor Algorithm The Repetitive Nearest-Neighbor Algorithm The Cheapest-Link Algorithm Robb T. Koether (Hampden-Sydney College)The Traveling Salesman ProblemNearest-Neighbor AlgorithmMon, Nov 14, 2016 6 / 15This video goes over the nearest neighbor and cheapest link algorithms to find shortest Hamiltonian circuits.22. Use the cheapest-link algorithm to find an approximate solution to the traveling salesman problem for the figure below. Also give the distance (assume units are miles). 23. A salesman must visit all four cities indicated in the figure below. Solve the traveling salesman problem by calculating the mileage for each possible route and indicating
Section 6.8: Cheapest-Link Algorithm. GOAL: Piece together a Hamilton circuit by individual edges or “LINKS” of graph trying to choose the smallest or “cheapest” weights first. The Cheapest-Link Algorithm for N Vertices: Step #1: Pick the edge with the smallest weight first. Mark the edge (or otherwise note that you have chosen it).1. We build the minimum spanning tree one edge at a time, choosing at each step the cheapest available edge. 2. The only restriction to our choice of edges is that we must never choose an edge that creates a circuit. - One difference from the Cheapest-Link Algorithm is that having three or more edges coming out of a vertex is now OK.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.For example, set D(x,y).optimalUp to true if going up from (x,y-1) results in the cheapest path. Then you can do a second pass to count the number of cheapest paths, using dynamic programming. Add another field, say D(x,y).count (integer) which holds the number of ways to go from A to (x,y) in the cheapest way.Kruskal’s algorithm works as follows: sort the edges by increasing weight; repeat: pop the cheapest edge, if it does not create cycles, include it in the MST; Two edges cannot construct a cycle in a simple graph; By the correctness of Kruskal’s algorithm, the two uniquely smallest weight edges are always part of an MST.
The Cheapest-Link Algorithm starts with the least weighted edge and integrates it into the circuit. Then it chooses the second-largest weight edge, and so on. We must avoid …1. We build the minimum spanning tree one edge at a time, choosing at each step the cheapest available edge. 2. The only restriction to our choice of edges is that we must never choose an edge that creates a circuit. - One difference from the Cheapest-Link Algorithm is that having three or more edges coming out of a vertex is now OK. algorithm in 1956). Kruskal’s Algorithm is nearly identical to the Cheapest Link Algorithm that is used for solving traveling salesman problems in weighted Hamilton circuits. Like the Cheapest Link Algorithm, the idea behind Kruskal’s Algorithm is to “piece together” an MST by choosing at each step the cheapest edge available. ….

Computer Science. Computer Science questions and answers. Questions: 1. Most expensive tour? We know that when solving a traveling salesman problem, using the Nearest Neighbor Algorithm or Cheapest Link algorithm will not necessarily produce the optimal (cheapest possible) tour as a solution. Is it possible that these algorithms could …Cheapest-link algorithm, using a table (1) Find the smallest number that is listed in the table and has not been circled or marked out.

Draw the corresponding edge on the map.
The next cheapest link available is BD ($150). Choosing BD would not violate either of the two rules, so we can add it to our budding circuit. Algorithm 4: The Cheapest-Link Algorithm 65 The Traveling Salesman Problem The next cheapest link available is AD ($152) and it works just fine.

Draw the corresponding edge on the map. Cheapest Link and Kruskal's Algorithms. The Cheapest-Link and Kruskal's are similar algoritms that perform dissimilar tasks on weighted graphs. A weighted graph is a graph whose edges have been assigned numbers - their weights.
