　　Inversion of kinematic parameters from scattered waves can lead to hard optimization problems,e.g.,when the measurements are interferometric,or when a background velocity needs to be estimated.I will explain how and when the semidefinite relaxation framework can be used to mitigate some of the nonconvexity inherent in these problems.Joint work with Augustin Cosse and Laurent Seppecher.
