First and foremost: I understand that all answers posted on Stack Exchange sites are required to be licensed under CC BY-SA 3.0 and that attribution is required. This is less of a licensing question and more of a site content question.
I have a practical problem that demands a creative solution, and I know that some of the most creative programmers frequent PP&CG, solving puzzles and doing gymnastics with code that are far more clever than anything I could come up with.
Would it be an acceptable practice for me to post said practical problem as a question, with the intent—clearly listed as part of the question, of course—to use the winning solution as part of an open-source project I'm working on?
To provide a little more context, the problem in question would fall into the proposed Data Golf puzzle category, similar to GeekWithALife's Smallest chess board compression challenge. The accepted answer would be in the form of a data format, and accompanying code would only be provided as a courtesy.
