> I had assumed that non-programming domain specialists would try producing some Petri net models using one of the most user-friendly cloud-based tools like NetLogo.
Right now I'm not working on any problems that make me interested in actually running Petri net models. I do appreciate all your work reviewing Petri net software and will include a chapter about that in the book (which keeps getting delayed, but I hope to finish this summer). But since I don't tend to use software for computation (just communication), I tend to avoid math problems where software would be useful.
This _might_ be something we could fix by working together, but it would require that both of us decide to do it, and communicate enough to make it happen.
