We study the problem of estimating the number of edges of an unknown, undirected graphG= ([n],E) with access to an independent set oracle. When queried about a subsetS⊆ [n] of vertices, the independent set oracle answers whetherSis an independent set inGor not. Our first main result is an algorithm that computes a (1 +ϵ)-approximation of the number of edgesmof the graph using · poly(logn, 1/ϵ) independent set queries. This improves the upper bound of · poly(logn, 1/ε) by Beame et al. [3]. Our second main result shows that /polylog(n) independent set queries are necessary, thus establishing that our algorithm is optimal up to a factor of poly(logn, 1/ϵ).
