We shouldn't be failing MINLPTests. They're intended to be "easy" to solve:

## Summary
I found an issue with `cyipopt`. If the objective sense of the model is minimization, the optimal duals provided by `ipopt` and `cyipopt` are opposite. Does this make sense?

## Summary
I am trying to create a model using the `pyomo.kernel` part of the library, and wish to use the `mindtpy` solver, however I'm coming into issues where it doesn't seem to be able to use t…

J'ai vu dans #168 qu'on pouvait utiliser ibexopt avec des variables entières en utilisant la contrainte floor.
les résultats que l'on obtient sont parfois un reel "proche" d'un entier.

Hi there,
the documentation advises to create on logical variable per `Disjunct`.
I am wondering, whether this can be simplified in the case of only two `Disjunct`s.
Maybe one can reduce the nu…

Hey @MilesCranmer !
I've been thinking about possible extensions and wonder how you think about this:
1. Parametric Operations
In short, I want to be able to supply function with hold tuneable…

I open this issue to discuss a more long-term subject: I wonder if we could include basic presolve operations into MatOI?
I think it would be easier to develop that inside this package instead of MO…
