What is a Minimum Spanning Tree? The cost of a spanning tree is the total of the weights of all the edges in the tree. For example, the cost of spanning tree in Fig. 3 is (2+4+6+3+2) = 17 units, whereas in Fig. 4 it is (2+3+6+3+2) = 16 units.. Since we can have multiple spanning trees for a graph, each having its own cost value, the objective is to find the spanning tree with minimum cost.

One algorithm for finding the shortest path from a starting node to a target node in a weighted graph is Dijkstra's algorithm. The algorithm creates a tree of shortest paths from the starting vertex, the source, to all other points in the graph. Dijkstra's algorithm, published in 1959 and named after its creator Dutch computer scientist Edsger Dijkstra, can be applied on a weighted graph.

We use the weighted shortest path wShortest and specify thecost_per_night property type as our weight. The weight lambda indicates the cost of expanding to the specified vertex using the given edge vst_per_night_USD, and the total cost symbol calculates the cost of the trip. The extract function is used to only show the city names.

Prim's algorithm to find minimum cost spanning tree (as Kruskal's algorithm) uses the greedy approach. Prim's algorithm shares a similarity with the shortest path first algorithms.. Prim's algorithm, in contrast with Kruskal's algorithm, treats the nodes as a single tree and keeps on adding new nodes to the spanning tree from the given graph.
