Cheapest link algorithm
Include the total coet for each circuit. As mentioned above, if there are two "cheapest links," i.e. two edges tie for the cheapest next edge and both are permissible under the algorithm, the algorithm gives no suggestions as to which edge to select as the next included edge. In that case, either edge may be chosen.The Cheapest-Link Algorithm Definition (Cheapest-Link Algorithm) TheCheapest-Link Algorithmbegins with the edge of least weight and makes it part of the circuit. Then it selects the edge of second-smallest weight, and so on. Once a vertex has two selected edges, no more edges of that vertex are considered and we must avoid creating a circuit ...Suppose the edge 𝑒 is the cheapest edge that crosses the cut (𝐴,𝐵). Then 𝑒 belongs to every minimum spanning tree. To my knowledge, all four options are correct. Options 1, 2 and 4 follow from the Cut property; option 3 is correct because edge weights are distinct. However, including option 1 is turning out to be wrong. Why?

Section 7. The cheapest link algorithm. In this method we don't choose a starting vertex. Instead we choose the “cheapest link” = the edge of smallest weight in the graph. Then we chooses the edge of second smallest weight .(this edge doesn't need to share a vertex with the previous edge). We keep doing this, except we reject any edges ... D. Cheapest-Link Algorithm.
