Some MILP solvers support computing multiple solutions (called *solution pool*) to a given MILP problem, but Sage lacks the ability to retrieve more than one solution from the solver (the existing `…

These are just some near term goals for after the initial alpha release
## Array tooling pieces
- [ ] More fancy formats
- [ ] Symmetric (padded and packed)
- [ ] Hermitian (padded and packed)

Hello,
I would like to start using t8code with Fenicsx/dolfinx. There is quite some work to interface the two libraries. One point on which I am unsure how to proceed is how to handle hanging nodes…

Dima:
* Numerical Optimization section should be split into parts. It's a weird mix of discrete optimization (Knapsack)--- out of place there, as it's not "numerical", but discrete, with numerical …

**What**
Diagnostics tooling to better understand model performance bottlenecks
suggestions by Daniel Tollenaar:
• Balance-error per basin: abs(Q * dt) - (dV)) / Vt-1, where Q is the nett in-/outfl…

**Problem:**
I am working in the field of ecosystem modelling.
A common constraints on the solution of a set of ODEs is positivity.
The most famous example of such a a set of ODEs is the [Lotka-Vo…

The root finders in `scipy.optimize` give different answers across operating systems and Python versions as has been seen in our unit tests in the [`./tests/`](https://github.com/PSLmodels/OG-Core/tre…
