**Feature description.**
In cases where the optimization is convex, use a convex programming interface such as CVXPy or GPKit instead of the current scipy.optimize.minimize SLSQP solver. This can spe…

Hi,
I would be interested in creating a Julia wrapper for parts of Siconos.
At the moment, the most relevant part for me would be **siconos/numerics (C)**, but later I would be interested in wra…

### Describe your issue.
When solving a simple piecewise-smooth system using the default configuration for solve_ivp (specifically rtol=1e-3 and atol=1e-6), the solution is significantly incorrect (o…

### Problem Description
I'm trying to solve a sparse __symmetric__ system;
Originally my matrix is CSC, square, only lower triangle is stored.
This is how I create sparse hip matrix:

Hi all.
I stumbled over a problem where Pulp is interpreting CBCs solution as `Optimal` whereas `CBC` itself logged
`Postprocessed model is infeasible - possible tolerance issue - try without p…
