This post was reworked by me to more accurately convey my point. This may have rendered some comments obsolete.
This question has a follow-up here.
There are quite a few questions wich could be answered by putting the question (or its title) into a google query and taking the first result. [just-google-it questions]
The main characteristics of these are
- The answer to the question is farily simple to obtain using google using the same words that appear in the question (So "How do I solve $\min \|Ax-b\|_2$?" doesn't meet this criteria because google will only find the answer given "ols" or "least squares" as additional input)
- The question may tend to be very localized (there used to be a close reason for this)
- The OP shows no effort at all (else he would have googled and found out the solution himself)
- Canonical answers (those not adding additional aspects to the question) will be short and localized as well, so they are unlikely to be of use for future visitors or other users reading the question
- Since google can find the answer, the question has a simple and concise formulation without the need of additional details
Questions I consider of the just-google-it type:
The wikipedia article on eigenvalues clearly deals (even with both kinds of) multiplicity.
Such questions should be closed to increase the overall quality of Math.SE, however none of the current close reasons seems to be to the point about the problem:
- Unclear what you're asking: Not really
- Not about Mathematics (within the scope): The on-topic list doesn't exclude such questions.
- Missing context: It's not missing context. The OP couldn't improve the question to meet the quality standards without asking a different (more general) question. See also What do we mean by "context"?
I see multiple options to improve the situation
Adding a new custom close reason
A possible close reason more applicable to such questions would be one discussed here or possibly another all-new custom close reason along the lines of
This question appears to be too local to your specific problem to be of future use. Please consider asking a more general question, providing your specific problem as a motivational context.
Changing what is on-topic
This would require a careful rewrite of our on-topic guidelines to exclude such questions. This however needs a precise and concise definition of a just-google-it question.
What do you think? Is the "Missing context" reason sufficient for such questions? Do we actually welcome such questions?
