I'm wondering whether it is appropriate to seek collaborators for Mathematica-related projects on Mathematica Stack Exchange. For example, would it be appropriate to post a question describing a potential Mathematica application, and ask if there are any parties interested in working on the application? Or should that be restricted to chat room discussions, if at all?

Alternatively, are there ways to search for Exchange members based on location, interest and expertise to facilitate collaboration? Would it then be possible to PM potential collaborators directly?

    1. There's no PM functionality in SE, this is by design. I'd personally prefer such discussions be confined to a chat room, but any programmming problem that comes up might be suitable for asking on main. – J. M.'s technical difficulties Jul 19 '16 at 14:27

    There's the chatroom, you can write about your ideas there. It may or may not be successful. MATLink is a collaboration born on this site. But I also made the IGraph/M package and suggested that people contribute. No one has. – Szabolcs Jul 19 '16 at 18:41

    Not appropriate on this site. You might try the Wolfram Community. – m_goldberg Jul 19 '16 at 20:46
  • @Szabolcs I use igraph thorough R. I did not know you had IGraph/M package. I will definitely take a deeper look since this would be a nice way to compare Mathematica and R. – Anton Antonov Jul 20 '16 at 14:28

    @Anton If you used my IGraphR package, I suggest you change to IGraph/M: it's much better. It's faster and better integrated. However, it doesn't cover all of igraph yet. It's a lot of work and I have little time. If there's specific functionality you need that it doesn't yet have, let me know, and I'll prioritize it. Though most of the work I do now on this project is contributions to the core igraph C library. The current IGraph/M release already includes things that the R and Python igraph interfaces don't yet have, and more is coming. – Szabolcs Jul 20 '16 at 14:34

    @Anton In particular, the following is new compared to the R interface: The Bliss library is updated to the latest version. It supports directed graphs and vertex colouring. It's much faster than Mathematica's (nauty based?) builtin for hard problems. Clique finding is much, much faster for all cliques (not maximal ones). It's also much faster than what's in Mathematica. What's coming: a big update for the LAD isomorphism finder which will bring at least a 6x speedup due to better memory management, as well as algorithmic improvements. Some more clique finding speedups are also on the way. – Szabolcs Jul 20 '16 at 14:38
  • @Szabolcs These points are really good to be aware of! I am going to compile graph-related things I have done or would like to do with graph-based recommenders and let you know. – Anton Antonov Jul 20 '16 at 14:55
  • Thanks all for the info and suggestions – obsolesced Jul 20 '16 at 15:21
