We establish nearly optimal sample complexity bounds for testing the clique property in the dense graph model. Specifically, we show that it is possible to distinguish graphs on n vertices that have a clique of size rho n from graphs for which at least epsilon n^2 edges must be added to form a rho n clique by sampling and inspecting a random subgraph on only O(rho^3/epsilon^2) vertices.

The new bounds for testing the clique property are obtained via a new extension of the graph container method. This method has been an effective tool for tackling various problems in graph theory and combinatorics. Our results demonstrate that it is also a powerful tool for the analysis of property testing algorithms.

This is joint work with Eric Blais.
