The limits of SDP relaxations for general-valued CSPs
It has been shown that for a general-valued constraint language Γ the following statements are equivalent: (1) any instance of VCSP(Γ) can be solved to optimality using a constant level of the Sherali-Adams LP hierarchy, (2) any instance of VCSP(Γ) can be solved to optimality using the third level o...
