We implement Algorithm 5 from https://arxiv.org/pdf/2403.04630v1.pdf

• Running the code in full_alg.ipynb will generate the "zoomed in" plots (i.e., $50{,}000$ time steps) for $D = 300$ that were presented in the rebuttal.
  • In the code right before "Generate Stream", setting block = True and deg_bd = 15_000 will make the block models described in the rebuttal.
  • Setting deg_bd = 1_000 will make the plots for $D = 1{,}000$ shown in the rebuttal.
• We use $\varepsilon = 1$, $\delta = 10^{-10}$, $T = 10^6$, $\beta = 0.05$.
  • These values can be changed immediately after the "Run Algorithm" header.

If the input graph is guaranteed to satisfy the degree bound, then chart_simulator.ipynb can be used to show what the added noise would be.

• WARNING: chart_simulator.ipynb is NOT PRIVATE and should only be used to compare the accuracy of our algorithm and other algorithms. (By contrast, full_alg.ipynb is private.)
• The charts produced by chart_simulator.ipynb are only correct if the input graph satisfies the specified degree bound.
