I have had a question up for two weeks now, had 4 votes and over 200 views but no comments or answers.
I have tried doing as mentioned in faq, especially had put some effort to "First, make sure you’ve asked a good question". This metaquestion is actually about putting more effort to that point :)
I have edited the question several times, as guided in the faq.
I have tried solving the question myself, to no avail.
I have asked two of my professors in my university, the author of the book containing the problem, few other webforums and some mathematical friends of mine. Still stuck.
I do not have enough reputation to set a bounty.
Now I will try here, hoping to educate myself and learn to ask the question in a better way.
So, what things should one take into consideration when formulating a question, in order to have the best odds of getting a good answer?
