    "abstract": "We express the optimization of entanglement witnesses for arbitrary bipartite\nstates in terms of a class of convex optimization problems known as Robust\nSemidefinite Programs (RSDP). We propose, using well known properties of RSDP,\nseveral new sufficient tests for the separability of mixed states. Our results\nare then generalized to multipartite density operators.",
