One of the nice features of Pyomo is that it is easy to walk the expression tree to generate different file formats.
I've had the occasion to do this several times recently, but I've noted that it'…

## Summary
There are many applications in which it is useful to generate a graph representation of a pyomo model using NetworkX. It would be nice to have a single common function/module in Pyomo wi…

Reading and writing Pyomo models to and from MiniZinc and FlatZinc files.
### Rationale
Pyomo & MiniZinc share similar goal as solver agnostic tools for specifying optimization pro…

Hi, are CNN sequential models from Keras supported?
For example if I insert a Keras "Conv2D" layer in the model, is the linearity of the model preserved and thus the possibility to embed in a MILP m…
