Sometimes one can use a fast numerical LP solver to solve a problem to "optimality",
then reconstruct the primal and dual solution in rational arithmetic (or over whatever base_ring was used...) an…

**Describe the bug**
Calling CVXOPT with a badly scaled SDP causes CVXPY to crash without any information.
**To Reproduce**
See minimum working code and data in the attached zip file. The matrix …

I am interested in a DG solver for hamilton-jacobi equations (of the form $`\varphi_t + H(\nabla \varphi) = 0`$) as they arise in level-set methods (e.g. $`H(\nabla \varphi) = a \| \nabla \varphi \|`$…

I have noticed an issue with immersed boundaries in the latest version of [Oceananigans](https://github.com/CliMA/Oceananigans.jl/releases/tag/v0.91.4). At the immersed boundaries we expect the defaul…

Hi!
I am using the latest version of the NESTML master branch, with the sine and cosine implementation.
I wrote two NESTML codes for stdp synapses, which present sine and cosine functions in the ke…

Thanks for your amazing work!
However, when I run your in-timestep-remeshing code, I encountered Segmentation fault (core dumped). I find that this bug encounters the first tim…

I am primarily using the cbc solver via the command line interface and was wondering if there is any easy way to set an "upper bound" for the objective value (minimization problem), to prematurely sto…

It would seem the very first checkpoint is not saved correctly.
Setting a very small example to save checkpoints at all time steps and attempting to restart to the very first checkpoint cause the s…
