We study the concept of propagation connectivity on random 3-uniform hypergraphs. This concept is inspired by a simple propagation algorithm for solving instances of certain constraint satisfaction problems. We derive upper and lower bounds for the propagation connectivity threshold. Our proof is based on a kind of large deviations analysis of a time-dependent random walk. Based on the analysis, we also give an upper bound on the expected running time of the simple propagation algorithm.
