Here are the steps for reproducing Table-A3, similar to others.\n\n* First, manually install two python libraries: ``skscope_experiment`` (provided the simulation data production method required for the experiment), ``parallel_experiment_util`` (convenient for running experiments with multiple processes). Note that these libraries are not available in Pypi, users should use `pip install ./skscope_experiment` and `pip install ./parallel_experiment_util`.\n\n* Next, run experiments like `python ./figure_A3/A3_skscope.py`, `python ./figure_A3/A3_gurobi.py`. Note that, gurobi need a license to run.\n\n* Finally, statistic the result by `./figure_A3/plot.ipynb`.\n\n## Citations\n\nPlease cite the following publications if you make use of the material here.\n\n- Zezhi Wang, Junxian Zhu, Xueqin Wang, Jin Zhu, Huiyang Pen, Peng Chen, Anran Wang, Xiaoke Zhang (2024). skscope: Fast Sparsity-Constrained Optimization in Python.
