This question already has an answer here:

I wanted to know answers to questions something like:

"A man wants to take his wolf and two sheep across the river using a boat in such a way that he can take only one animal while travelling on the boat from one side to another side. Wolf eats sheep in the absence of the man. What does man do without wolf causing any harm?"

Where can I ask these kind of questions please?

    To me, that sounds like something that would be asked at Puzzling. But I would check what's acceptable there first. – Jason Bassford Jul 17 at 18:04

The closest SE site I see you can go to is

SE Puzzling

Be sure that your question meets this site's policies though 1st please.


Also note that I won't consider your example a "common real world logic problem"1, that stuff is already well known and purely hypothetical.

Your example question probably would get downvoted and closed as duplicate at that site. Here's one (duplicate) example I found quite quickly:

When do missionaries and cannibals problems have solutions?

I think the answers show the principle how to solve that problem quite well.

I'd say you'll need to flesh out the "real world context" more to ask there.


1)Note that any kind of logical problems can be reduced to more or less simple math, unless they can't be identified as NP problems

    very few puzzling questions are real-world. The problem with the wolf/sheep problem is not it's artificiality (take a look at puzzling's liars tag) but that even a cursory search would find duplicates. Logic problems that are not just math are on topic on puzzling. – Kate Gregory Jul 17 at 18:52
  • @Kate Sure. I just wanted to make a clarification regarding the NP problems always can be reduced to math. I didn't say the non NP problems are off-topic at that site. I even don't have any experience about it :-D. – πάντα ῥεῖ Jul 17 at 18:54
