Maximum Gradient Embeddings and Monotone Clusteringgs, which we call ., yield a framework for the design of approximation algorithms for a wide range of clustering problems with monotone costs, including fault-tolerant versions of .-median and facility location.

https://doi.org/10.1007/978-3-642-69817-0provide a family of simple examples for negative type metrics that cannot be embedded into ℓ. with distortion better than 8/7 − .. To this end we prove a new isoperimetric inequality for the hypercube.
