Here is my proposal: We do not want hint-only answers. If a question does not deserve a full answer (now), don't answer (now). Use the comment feature for providing hints. Down- and/or close-vote the question if and as appropriate, i.e. in accordance with current policy. If you happen upon a hint-only answer, kindly refer the author to this ...

Many, even most, of the questions on this site are homework questions. Despite the homework policy, in practice the site is used mainly to help students with their homework, and indeed traffic varies predictably with the academic year. If you discourage such questions, traffic would decrease dramatically. While the homework policy suggests that we do ...

Quality vs Quantity? and at this time I think Quantity is more important. NO. Quality is always important. You cannot grow a site by favoring quantity over quality. If you make the site boring for experts, the experts will leave! It's normal for a Stack Exchange site to start out at a slightly higher level than the final target, when most of the ...

I think the issue can be resolved through rigorous semantics. A "question" in the form "I don't know where to even start, please help!" Isn't really a question at all. It's a request for help. Bad questions in this form can be edited into the form "What are the initial steps for starting to solve the problem...". This form has two advantages: 1) it is ...

I would suggest that you start by reading the Wikipedia article on NP and reading your textbook chapter on NP. That should explain how to do this problem, and it'll probably even give some examples of how to prove that other problems are in NP -- which you can try to apply to the Knapsack too. That will be a good test of whether you understand the definition ...

EDIT THE QUESTION Most visitors find threads on Stack Exchange after searching on Google. Google gets us about 85% to 90% of our traffic. Other search engines, and searches inside Stack Exchange, only account for a small minority of the traffic. So if you want a question to be found, make sure that Google finds it. I don't know how much attention Google ...
