The solution discusses feature differences and tradeoffs.

##### Solution Preview

Depth-first search (DFS) is memory efficient, but typically finds goal states only very deep in the search space which leads to very long counterexamples.

Breadth-first search (BFS) is complete and can provide shortest counterexamples. However,

BFS is in general too memory inefficient to be applied to models of realistic size.

In graph theory, a topological sort of a directed acyclic graph (DAG) is a linear ordering of its nodes which is compatible with the partial order R induced on the nodes where x comes before y ...
