POWELL is definitely misbehaving!
ITER and ITMAX are not updated or have any effect. Xi initial/final set of directions is not updated.
Optimization quality…

I think this could be another case of #20360.
Consider this snippet:
```python
>>> from sympy import *
>>> from sympy.abc import x
>>> a = symbols('a', positive=True)
>>> expr = (1 + a * cos(x…

Currently the iterative solvers try to reach the prescribed accuracy. If it
stagnates for a (very) large number of iterations, it stops and produces an
error.

I am trying to get to using the spectral solver with PML boundaries. I run into a problem is when the laser diverges after the focus the beam interacts with the boundary and generates spurious reflect…

Hi Katherine,
Thank you for your great work on supporting DPM-Solver++, and I've found that it has been used in stable-diffusion-webui and has a great performance: https://github.com/AUTOMATIC1111/…

Models with conditional expressions within `noEvent()`, possibly obtained by processing the `smooth()` operator, can cause solver issues. The macroscopic observed behaviour in some cases is that the s…

Currently, I'm writing a quadratic minimization problem that looks like this (an example from [matlab](https://www.mathworks.com/help/optim/ug/quadprog.html?s_tid=srchtitle_quadprog_1&requestedDomain=…

### What happened?
Given a list of points along a path, I've constructed a smooth trajectory through those points with `PiecewisePolynomial.CubicWithContinuousSecondDerivatives`, and then passed th…
