I asked a question on SO: How to implement an agent?. I got unhelpful comments/answers, I've learned nothing, and I don't have the faintest clue how to improve my question. Some people are more interested in telling others they are wrong than in leaving helpful hints about how they could reformulate a question properly. That is sad and definitely doesn't help improve the quality of content on Stack Overflow.
In general, SO is not a good place to look for advice on how to start something; specific problems fare much better. The FAQ says:
Your questions should be reasonably scoped. If you can imagine an entire book that answers your question, you’re asking too much.
There are indeed entire books written about the basics of artifical agents. I don't think the problem is with your writing so much as the actual question. I see you've tried to update it with hypothetical details, but it's still incredibly broad. The best advice for you is probably to read some books on the subject and/or take a course, which wouldn't constitute much of an answer either; self-contained and detailed/complete answers are best for SO. It just doesn't fit.
