One question: Is there any need to add non-regression tests for these improvements?

Whenever this parameter is None, it is somehow causing the tests to fail while the default parameter (1,1) works fine with these modifications. I tried to debug the defualt_location method but it seems fine! I am a little confused why the tests are failing...

Alright, due to the random placement of things in the Wumpus agent environment, the agent dies due to this line:
Line 958 in fbdb36d
| if isinstance(agent, Explorer) and self.in_danger(agent): |
I think the only choice is to let the parameter location as is for now.

LGTM. @antmarakis
Please suggest improvements, if any!

Hmm... So, the thing that was causing tests to fail was the random seed. Changing it across a couple of tests was just about it! The code is up and running fine!

Thanks for the contributions, much appreciated!
Changing the random seed isn't really fixing the problem though, but masking it.
Maybe the problem though is not with your changes but with some other piece of code. I suggest you try using different seeds on the original code (before your changes) and see what happens.

I tried many different seeds and these are the results I got:
- When the seed is set to
"aima-python"globally, all the tests pass. - When the seed is set to
"aima-python"individually in each function,test_WumpusEnvironmentActionsfails (reason: agent dies due toPitorWumpusobject atagent.location) - When the seed is set to
9for the testtest_WumpusEnvironmentActions, the tests pass.
I think there is no problem with the code but the random placement of things is affected due to the seed in Wumpus environment and so the agent dies.
The code is available at this branch of my fork.
