 Our paper "Revisiting Local Computation of PageRank: Simple and Optimal" has been officially [published](https://dl.acm.org/doi/10.1145/3618260.3649661). Unfortunately, I cannot attend the [STOC 2024](https://acm-stoc.org/stoc2024) conference in person, due to the exceptionally and unreasonably long processing time of my visa application to Canada. :disappointed:
