Benchmark examples for the PROXQP solver

These are the scripts to compare the following Quadratic Program (QP) solvers

  • PROXQP (with dense backend)
  • OSQP
  • GUROBI
  • MOSEK
  • qpOASES
  • quadprog

The whole API comes from the one developped by the authors of OSQP. We thank them a lot for their rigorous approach.

The detailed description of these tests is available in this paper.

To run these scripts you need standard python libraries: pandas, matplotlib, numpy, scipy, scikit-learn, and cvxpy, which can be installed using for example conda:

conda install pandas matplotlib numpy scipy cvxpy scikit-learn

You need further as well to install the solvers gurobi, mosek, OSQP, quadprog and qpOASES. The first four can be installed for example using conda:

conda install -c gurobi gurobi
conda install -c mosek mosek
conda install -c conda-forge osqp
conda install -c omnia quadprog

Gurobi and Mosek require a license for working. Note that if you are an academic, they provide specific and temporary free licenses.

Finally, for installing qpOASES, you should look at their install file in their github repository.

All the scripts come with options (default to False)

  • --parallel for parallel execution across instances
  • --verbose for verbose solvers output (they can be slower than necessary while printing)
  • --high_accuracy for high accuracy eps=1e-09 solver settings + optimality checks

Note that the parallel option has not be tested for the paper benchmarks.

Benchmark problems

The problems are all randomly generated as described in the ProxQP paper. Problem instances include

  • Inequality and Equality Constrained QP,
  • Pure Inequality Degenerate QP,
  • Pure Inequality QP without strictly convex Hessian matrix.

We generate the problems using the scripts in the problem_classes folder.

To execute these tests run

python run_benchmark_problems.py

Results

For Convex Quadratic Programs with inequality and equality constraints, when asking for a high accuracy (e.g., 1.E-9), the resulting shifted geometric means are, for dense problems

PROXQP quadprog OSQP GUROBI MOSEK qpOASES
1.0 20.4 18.2 5177.8 38131.0 282.6

and for sparser one (i.e., a ratio of sparsity of around 15%)

PROXQP quadprog OSQP GUROBI MOSEK qpOASES
1.0 19.3 3.5 6938.0 76844.2 260.6

These results have been obtained with a 11th Gen Intel(R) Core(TM) i7-11850H @ 2.50GHz CPU.

Maros Meszaros problems

These are the hard problems from the Maros Meszaros testset converted using CUTEst and the scripts in the maros_meszaros_data/ folder.

To execute these tests run

python run_maros_meszaros_problems.py

Results

The resulting shifted geometric means are when asking for a high accuracy (e.g., 1.E-9)

PROXQP quadprog OSQP GUROBI MOSEK qpOASES
1.0 105.8 14.2 114.2 194.9 4.5

maros_meszaros_problems_high_accuracy

At lower accuracy (e.g., 1.E-3), the resulting shifted geometric means are

PROXQP quadprog OSQP GUROBI MOSEK qpOASES
1.0 1543.3 108.5 637.3 175.3 17.1

These results have been obtained as well with a 11th Gen Intel(R) Core(TM) i7-11850H @ 2.50GHz CPU.
