Appendix

Appendix A contains details on the experiments conducted throughout this paper. Details regarding the datasets used in the experiments are included in Table 2. All of the attacks are run on an Ubuntu (16.04) cluster with Y ang et al. [2020] uses Gurobi as the solver. For GeoAdEx, we choose to compute distance to cell and set m to 20 and applied a time limit of 100 seconds per test point. Wang et al. [2019] is generally the fastest, and GeoAdEx is faster than Y ang et al.
