TL;DR
Euclidean embeddings of Euclidean metrics are studied to present an O(log3 n√log log n) approximation for minimum bandwidth in conjunction with a semi-definite relaxation and a lower bound on the least possible volume distortion for Euclidan metrics.
Abstract
We study Euclidean embeddings of Euclidean metrics and present the following four results: (1) an O(log3 n√log log n) approximation for minimum bandwidth in conjunction with a semi-definite relaxation, (2) an O(log3 n) approximation in O(n log n ) time using a new constraint set, (3) a lower bound of Θ(√log n) on the least possible volume distortion for Euclidean metrics, (4) a new embedding with O(√log n) distortion of point-to-subset distances.
