Hey,
thank you for this great package. I have a problem using the scipy LSODA solver together with odeint_adjoint for a nonlinear stiff ODE. The problem is the following:
1. The forward solve w…

Hi,
I have a working version of BDF solver in JAX with JIT support which I ported from tensorflow_probability. I tested it with stiff chemical kinetics problems using VODE wrapper in SciPy and the r…

Dear Devs,
I've come up against an extremely stiff set of ODEs, which are solved - apparently accurately - by some closed source FORTRAN. I'm attempting to find an algorithm that is able to match t…

We should try to finish up the standard problems.

I haven't found yet any solvers for stiff manifold ODEs but maybe there are some?

Hi Patrick
I am trying to calculate the first order sensitivity w.r.t. to all the three kinetic parameters for the Robertson Equations using `diffrax`. I am using the stiff ODE example provided [he…

VPLanet would probably be ~10x faster, and a more flexible if it used a production quality ODE solver. I think [LSODA (this is link to C version)](https://github.com/sdwfrost/liblsoda) is a good optio…
