QPALM is a numerical optimization package that finds stationary points of (possibly **nonconvex**) quadratic programs, that is
```
minimize 0.5 x' Q x + q' x
subject to l <= A x <= u
```
## Documentation
You can now find the the documentation [here](https://benny44.github.io/QPALM_vLADEL/). This includes all information you need to get started using QPALM.
## Benchmarks
Check out the paper below for detailed benchmark tests comparing QPALM with state-of-the-art solvers.
