dolfinx_optim

dolfinx_optim is a convex optimization add-on package to the FEniCSx finite-element library. It provides a simple Domain-Specific Language through FEniCSx dolfinx Python interface for solving convex optimization problems. In particular, it relies on the Mosek mathematical programming library. Mosek provides a state-of-the art interior-point solver for linear programming (LP), convex quadratic programming (QP), second-order conic programming (SOCP) and semi-definite programming (SDP).

Prerequisites

dolfinx_optim requires:

• FEniCSx (v.0.8), see installation instructions here.
• MOSEK (>= version 10 with its Python Fusion interface), see installation instructions here. The Python interface can be simply installed via pip:

pip install -f https://download.mosek.com/stable/wheel/index.html Mosek

Mosek is a commercial software so users need a valid Mosek license. Free unlimited licenses are available for education and research purposes, see the Academic License section.

Installation and usage

Simply clone the dolfinx_optim public repository

https://github.com/bleyerj/dolfinx_optim

and install the package by typing

pip install dolfinx_optim/ --user

Features

Current version supports variational problem formulations resulting in Linear Programs, Second-Order Cone Programs, Semi-Definite Programs and Power or Exponential cone programs.
