On the local and global minimizers of the smooth stress function in Euclidean Distance Matrix problems

Mengmeng Song, Douglas Goncalves, Woosuk L. Jung +3

We consider the nonconvex minimization problem, with quartic objective function, that arises in the exact recovery of a configuration matrix $P\in {\mathbb{R}}^{nd}$ of $n$ points when a Euc…
