As an example I asked a question where the title could have been phrased better - that is, it wasn't phrased as a question; however, the body of the entry was a question about what options are available for creating controllers for agents in simulated worlds.
The item was closed ("Not a real question"), I have subsequently rephrased the title and body but now I still need 3 votes to reopen.
The question I'm referring to is: What types of solutions are applicable to real-time controller tasks?
Potentially this is on the edge of what SO is meant for. The reason I thought it would be OK was that it is about programming, it is a question with some potentially straightforward direct answers (although there is obviously scope for wider and open ended discussion) and there are pre-existing 'challenge' and code-golf questions that seemed to be popular and that haven't been closed.
Any thoughts welcome. Thankyou.
