For generating the figures in the paper please execute the following codes:

1. run the instances to generate the required experiment results data

nohup bash execute.sh &

2. run summarize.py to collect all the statistic from the experiments meta-data

python3 summarize.py

3. run plot-curves-paper-p1.5.ipynb/plot-curves-paper-pinf.ipynb/plot-curves-bandit.ipynb to generate the figures and tables for the "p=1.5"/"p=inf"/"bandit" part.

run summarize_table.ipynb notebook to generate the Table 1 and 2 in the paper.
