A list of OR Software forums would be nice.

Can someone import the list of OR Software forums from the (now) read-only OR Exchange at https://www.or-exchange.org/questions/9068/or-software-forums ?

Can you please delete extinct software, add additional software, and update links to be current?

    $\begingroup$ Should be moved to our Meta, as a FAQ. $\endgroup$

    $\begingroup$ @Rob I disagree. Regular people looking for info on SE don't look at meta. As far as i know, it would not show up using the search box on or.stackexchange.com . Is it possible to have FAQ on the main OR SE site? $\endgroup$ Commented Jun 16, 2019 at 10:50

    $\begingroup$ "Regular people" should know to look to Meta, for FAQs (or perhaps this is an iFAQ). Google will find it, main - no. The other close vote is for "too broad", which I don't disagree with, mine is for 'move to Meta' (which keeps it open). On SO there are a couple of similar questions: meta.stackoverflow.com/questions/254674/… and meta.stackoverflow.com/questions/294364/… which were downvoted out of existence. We'll see. $\endgroup$

Here is the augmented and updated list. This should be a good starting point for further improvements.

This list is very optimization-heavy (even the automatic differentiation software is most likely to be used by O.R. people in support of nonlinear optimization). So perhaps some additions outside optimization would be warranted, as well as machine learning tools.

  • $\begingroup$ @TheSimpliFire Can you fix the formatting? When I edited it yesterday, the formatting got screwed up. It was o.k. before I edited it. Even the older versions now have screwed up formatting, so rolling back the version didn't help. i don't know what happened. Thanks. $\endgroup$ Commented Aug 14, 2020 at 18:04
