Rate-optimal community detection near the KS threshold via node-robust algorithms arXiv:2511.16613v1 Announce Type: new Abstract: We study community detection in the emph{symmetric $k$-stochastic block model}, where $n$ nodes are evenly partitioned into $k$ clusters with intra- and inter-cluster connection probabilities $p$ and $q$, respectively. Our main result is a polynomial-time algorithm that achieves the minimax-optimal…
