Based on the corresponding LP relaxation and dual program, we propose a primal-dual 3-approximation algorithm. Combining the greedy augmentation procedure, we further improve the above approximation ratio to 2.

In the particular case of semidefinite optimization, an explicit expression for the dual cone of the minimal cone allows for a dual program of polynomial size that satisfies strong duality. This is achieved due to the fact that we can express the orthogonal compleme
