In this chapter, we learned about "weighted" graphs (graphs with numbers called "weights" on each of its edges), and we learned about two special types of weighted graphs:

• Minimum Hamilton Circuit:  a circuit which visits each vertex in a graph exactly once (returning to the starting vertex) and which has the smallest total weight
• Minimum Spanning Tree:  a subgraph of the original graph which is a tree, which includes all vertices in the original graph, and which has the smallest total weight

Please research and find an example of how one of these can be applied to solve a real-world problem and report your findings.
