Solving a maze isn&#x27;t identical to Dijkstra&#x27;s algorithm.  And Dijkstra&#x27;s algorithm was specifically chosen to be an easy problem with an understandable answer, to show off a new computer.  It was never some grand unsolved problem.  Yes, it&#x27;s reasonable to expect somebody with a modern data structures education who mysteriously hadn&#x27;t heard of it to be able to invent it.  Or to reinvent it, having forgotten it, because it&#x27;s your basic breadth first search with care taken not to get &quot;lost in the woods.&quot;
