In this paper, we develop a new variant of k-means++ seeding that in expectation achieves a constant approximation guarantee. We obtain this result by a simple combination of k-means++ sampling with a local search strategy.

We evaluate our algorithm empirically and show that it also improves the quality of a solution in practice.
