pyomo-MINLP-benchmarking

What is this?

This repository mostly contains the run_benchmarks.py script as well as a collection of MINLP problems/models, which have been taken from the MINLPlib and converted to Pyomo models with the translate.py file.

Example usage

When running

python run_benchmarks.py -h  # show some help
python run_benchmarks.py --solver mindtpy --model-dir models
# or, when re-running
python run_benchmarks.py --solver mindtpy --model-dir models --redo-existing --no-skip-failed

After running, the results/<solver> dir will contain

• a .txt file for each model output
• trace_file.trc which can be loaded into Paver to generate automatic benchmarking plots (not yet tested)
• solving_times.csv which contains the model name, aswell as the solving time or the termination condition/error
