As noted elsewhere, this is already an issue needing work.
Running the percept function after initializing the HybridWumpusAgent object resulted in an NameError. It seems there were no Percept classes to compare with, so I changed it to compare with Expr of different Percepts and fixed a typo.

After that I tested it by running execute function. It just does not stop running, gets stuck on resolving a huge list of clauses. The grid of the Wumpus agent is 5, making lots of clauses.
Any ideas on optimizing the given methods?
