Generalizations of doubly nonnegative cones and their comparison

In this study, we theoretically and numerically compare several generalizations of the doubly nonnegative (DNN) cone, which is frequently used to provide a relaxation that is tighter than that of the positive semidefinite cone for completely positive programming (CPP). To provide tighter relaxation for generalized CPP (GCPP) than the positive semidefinite cone, we generalize the … Read more
