Question:
Give an
example of a directed graph G = (V, E), a source vertex s V, and a set of tree edges Eπ ⊆ E such that for each
vertex v V, the unique path in the graph (V, Eπ) from s
to v is a shortest path in G, yet the set of edges Eπ cannot
be produced by running BFS on G, no matter how the vertices are ordered in each
adjacency list.
