A Tight Algorithm for Strongly Connected Steiner Subgraph on Two Terminals with Demands (Extended Abstract),nimum weight such that . contains a . path for each .. The problem is NP-hard, but Feldman and Ruhl [FOCS ’99; SICOMP ’06] gave a novel . algorithm for the .-SCSS problem..In this paper, we investigate the computational complexity of a variant of .-SCSS where we have demands for the number of paths

AND-compression of NP-complete Problems: Streamlined Proof and Minor Observations,s for the compressibility and kernelizability of a whole range of NP-complete parameterized problems. We present a streamlined proof of Drucker’s theorem..An AND-compression is a deterministic polynomial-time algorithm that maps a set of SAT-instances . to a single SAT-instance . of size . such that
