Thank you for your reviewing!

=======================================

1. We provide most part of our code in the key-code folder. The implementation of our algorithm can be found in ./key-code/prune.

2. We also provide experimental code and results in the Jupyter Notebook format, which can be found in ./notebooks folder. If you haven't installed the tool to view the *.ipynb, we recommand using Jupyter Notebook Viewer (https://github.com/tuxu/nbviewer-app) or Google's Colaboratory (https://colab.research.google.com/).
