Abstract of a paper by Afonso S. Bandeira, Edgar Dobriban, Dustin G. Mixon, and William F. Sawin
This is an announcement for the paper "Certifying the restricted isometry property is hard" by Afonso S. Bandeira, Edgar Dobriban, Dustin G. Mixon, and William F. Sawin. Abstract: This paper is concerned with an important matrix condition in compressed sensing known as the restricted isometry property (RIP). We demonstrate that testing whether a matrix satisfies RIP is hard for NP under randomized polynomial-time reductions. Our reduction is from the NP-complete clique decision problem, and it uses ideas from matroid theory. As a consequence of our result, it is impossible to efficiently test for RIP provided NP \not\subseteq BPP, an assumption which is slightly stronger than P \neq NP.
