Approximation hierarchies for copositive cone over symmetric cone and their comparison

Mitsuhiro Nishijima, Kazuhide Nakata

We first provide an inner-approximation hierarchy described by a sum-of-squares (SOS) constraint for the copositive (COP) cone over a general symmetric cone. The hierarchy is a gen…

Generalizations of doubly nonnegative cones and their comparison

Mitsuhiro Nishijima, Kazuhide Nakata

In this study, we examine the various extensions of the doubly nonnegative (DNN) cone, frequently used in completely positive programming (CPP) to achieve a tighter relaxation than…
