# What to do if your best questions are getting downvoted?

Recently, I have asked a question and made sure that I provided enough details showing that I somewhat understand what I'm reading.

Overall, what details should be omitted that make the question easier to understand?

• If you check parity of the number and provide only odd numbers as test suite, do you think it is co-np, because all answers are no?

• @Evil Presumably my intentions are wrong as the Wikipedia definition is summary that leaves out important details. After, all there has to be a mathematical definition. And, wikipedia is getting it wrong(an unreliable source right now). Yes, I think it could be co-np because ALL answers are no. Commented Apr 28, 2019 at 4:13
• @Evil All answers that are no are from non-constrained Sudoku Grids. Commented Apr 28, 2019 at 4:16
• @Evil . In other words, co-NP is the class of problems for which there is a polynomial-time algorithm that can verify "no" instances. My algorithm in essence is the English Dictionary defined summary. However, the mathematical reference I don't know. Commented Apr 28, 2019 at 4:35
• @Evil I've undeleted one of my old questions, I was wondering if you could answer it. cs.stackexchange.com/questions/108480/… Commented Apr 28, 2019 at 5:19
• This is not a full answer, but I want to repeat D.W.'s advice at the end of this post to you. You are trying to solve complicated problems without fully understanding the definitions to formulate these problems properly. I would strongly advise you to first master the fundamentals, by reading a book or online course in basic complexity theory and/or algorithms. I'm afraid that you simply lack the knowledge to ask good questions about the topics you want to ask about, otherwise.

This is somewhat improvement, but please, take a step back with your attempts. Pick a book, read questions here, take some course and learn basics. It cannot be done in one or two days, human brain needs three days to acquire concept and a week to remember it, with exercise execution when you keep revising every day. Otherwise, it will be shallow concept lost from memory in less than month.

There is a quote from Wikipedia, a summary of your attempt, your algorithm and still you try to merge complex concepts with your idea, and it does not stick.

I fully understand why, it is easier to grasp concepts through something close and familiar, but here unfortunately you really need to let it go and learn differently.

You have given a summary here in the comments, but all the time your questions are in the terms of your generator.
