No, do a best-first-search and copy the original graph to a new graph. The
new graph should be an excact copy of the original, except the nodes are
labelled with their least total cost from the start node.

the point is that in a best-first-search, each edge is only traversed once.
This makes it appropriate for copying the graph, too.
