seems to be a meta-tag. I looked through some of the questions and it only seems to be used for a (subjectively) very complex problem.

207 49 questions are tagged with it.

  • I cleaned up this tag, it should be made a [synonym of complex-numbers] now

has some disambiguities, not sure what to do with that:

Tasks (see Giles answer):

  1. cleanup everything in and that does not refer to complex numbers / the xml complex data type Done
  2. make a synonym of

Someone needs to to the synonymizing now.

EDIT May/2012 I just cleaned up some questions from again. The tag is still likely to be misused with "complex sql queries", "complex anything stuff" and "the complex xml type"

  • Good call! I bet there's a simple or easy tag as well.

  • @Pekka'sReputationBordello nope :D and difficult neither.

  • @Pekka'sReputationBordello I think these were burninated in an earlier purge. There's a simplify, which is mostly meta but might have a few occurrences about the theorem prover or a function in some computer algebra systems (e.g. 1 2). Commented Mar 8, 2012 at 12:15

Whoa there, many questions use it to mean complex numbers, which is also covered by . There's also which at a first glance looks like a mixture of complex numbers and complicated types.

I propose the following:

  1. Go through and , removing the tag when it's used as a meta-tag.
  2. Make a synonym of , which should reduce its misuse.

As I write: 207 × , 58 × , 74 × . I propose to keep , even though it's the minority, because it's clearer.

  • There's also one occurrence for complex network (yes, this is a technical term). Commented Mar 8, 2012 at 12:20
  • wouldn't it be easier to retag everything that is not the meta tag and burninate the rest? Do we really need a complex tag, that can be misinterpreted?

    @örs Maybe, but I don't think the misuse is so widespread, I'd prefer to save complex for complex numbers. Commented Mar 8, 2012 at 12:39
  • okay, I'll go ahead and retag those questions in the next few days.

  • I cleaned up the [complex] tag. Can you make it a synonym of complex-numbers?
