Abstract:We study the problem of estimating the number of edges in an n-vertex graph, accessed via the Bipartite Independent Set query model introduced by Beame et al. (ITCS '18). In this model, each query returns a Boolean, indicating the existence of at least one edge between two specified sets of nodes. We present a non-adaptive algorithm that returns a (1 ± ǫ) relative error approximation to the number of edges, with query complexity O(ǫ −5 log 5 n), where O(•) hides poly(log log n) dependencies. This is the first … Show more
