Efficient algorithms for k-means clustering frequently converge to suboptimal partitions, and given a partition, it is difficult to detect k-means optimality. We discuss an a posteriori certifier of approximate optimality for k-means clustering based on Peng and Wei's semidefinite relaxation of k-means.
