Linear-Delay Enumeration for Minimal Steiner Problems
Summary: Linear-delay, polynomial-space algorithm to enumerate all minimal Steiner trees in directed graphs, improving Kimelfeld & Sagiv; extends to Steiner forests, terminal and directed variants. Also: polynomial-delay, exponential-space enumeration for minimal induced Steiner subgraphs on claw-free graphs; hardness result showing enumeration of minimal group-Steiner trees is at least as hard as minimal hypergraph transversal enumeration.
