Fixed-Parameter and Approximation Algorithms: A New Look,2]-hard problem is known to have a polynomial time .(OPT)-approximation for any function .. Finally, we answer a question by Marx by showing the well-studied Strongly Connected Steiner Subgraph problem (which is W-hard and does not have any polynomial time constant factor approximation) has a constant factor FPT-approximation.Conjuction 发表于 2025-3-27 12:55:01
