QPALM is a numerical optimization package that finds stationary points of (possibly nonconvex) quadratic programs, that is
\begin{equation*}
\begin{aligned}
& \underset{x}{\textbf{minimize}}
& & \tfrac12 x^\top Q x + q^\top x\\
& \textbf{subject to}
& & b_\mathrm{min} \le Ax \le b_\mathrm{max} \\
\end{aligned}
\end{equation*}
Documentation
The documentation can be found at: https://kul-optec.github.io/QPALM/Doxygen
Examples are included as well: https://kul-optec.github.io/QPALM/Doxygen/examples.html
Installation
Python
The QPALM Python interface is available from PyPI, you can install it using:
python3 -m pip install qpalmJulia, Matlab, C/C++/Fortran
Installation instructions for the Julia, Matlab, C, C++ and Fortran interfaces, as well as instructions for building QPALM from source, can be found on GitHub.
Supported platforms
QPALM is written in C, with interfaces for C++, Python, Julia, Matlab and Fortran. The code itself is portable across all major platforms. Binaries are available for Linux on x86-64, AArch64, ARMv7 and ARMv6, for macOS on x86-64 and ARM64, and for Windows on x86-64.
Benchmarks
Check out the papers below for detailed benchmark tests comparing QPALM with state-of-the-art solvers.
