We disprove this conjecture by constructing a planar graph on twelve vertices tha

Most of algorithms use randomization and achieve the approximation ratio as the expected value. For unconstrained submodular maximization, [Buchbinder and Feldman 2016] gave a derandomization scheme, and sho

Six Sigma Performance Measurement System. The relationships that we present relate to a long-standing open problem concerning whether any pair of these problems are polynomially equivalent for every graph. The relationships we present also relate to the constraint satisfaction problem, providing evidence that similar to the compaction and
