Area 51 » Science

Downvoting this question because guidelines say we should "Avoid asking questions that are subjective, argumentative, or require extended discussion. Stack Exchange does not work well with questions like 'Which is the best…'". area51.stackexchange.com/faq Feel free to reword the question. – LarrySnyder610 Apr 1 '19 at 19:19

@LarrySnyder610 Has this question been edited subsequent to your comment? It seems like a perfectly fine question as currently shown, and I could give a great and comprehensive answer to it, to include adding material for "matrix exponential" cone (using CVXQUAD). Even if it asked for which was best, that doesn't seem like the crime of the century to me, so perhaps I'm not Operations Research and Analytics Stack Exchange material. – Mark L.

@Mark L. Stone yes, the question-asker revised the question after my comment. The original question was something like "What is the best solver for ..." So the question is good as it is now, in my opinion. About asking "what's best," I agree it's not the crime of the century, but SE discourages it, and I think the more we can stick to SE guidelines and norms, the better chance we have. But I disagree you are not OR&A SE material -- I think SE works best when there are multiple voices and multiple opinions/answers. Please stay with us! – LarrySnyder610 Apr 2 '19 at 14:33

@LarrySnyder610 There is such a thing on SE as Community Wiki. Many of those questions and answers are very useful. "What's the best" questions can fall within Community Wiki in my opinion. – Mark L. Stone Apr 2 '19 at 14:52

Yes, as @LarrySnyder610 says, I changed the question to not say "best." I personally think that "best" was maybe even better; if I am going to an OR Stack Exchange I am often looking for opinions from people with more experience dealing with, e.g., exponential cones in practice. Still, making the question more generic by just asking for options seems fine. – Christian Kroer Apr 2 '19 at 20:09

This question would be stronger if it were more specific, e.g., "what are the ways that nonconvex optimization is used in ML" or something like that. – LarrySnyder610 Apr 1 '19 at 19:21

That makes sense. I have edited the question to make it concrete, something a student / researcher / practitioner may ask. – akazachk Apr 1 '19 at 20:52

For posterity, my old question was "What are the open source integer programming solver alternatives with the best performance?" This could be a good Community Wiki question, after reading the discussion on Christian's post. Though thinking a bit more on it, I think the original question was not so subjective / argumentative. It may require some extended discussion, but there are commonly accepted benchmarks that can be referred to. It would still be good to make it a Community Wiki in order to make it easier to update over time, since a normal "question" will have a fixed accepted answer. – akazachk Apr 2 '19 at 15:57

I think the original question is good. Make it Community Wiki or whatever, but I think this kind of question should be encouraged, not discouraged. Let people answer with thieir opinions and preferences, with whatever explanation they care to provide. Operations Research itself doesn't lend itself to clean unambiguous answers. – Mark L.

Do you mean "How do I model a single exclusive-OR choice or a single inclusive-OR choice in mixed-integer programming?" If this is not what you mean, could you write a more clear question? – alerera Apr 3 '19 at 13:39
