description
3 (Undirected) Steiner Tree (ST) Instance: A graph G = (V,E), a cost function c: E +, and a set D V. Objective: Find a subgraph H G of minimum cost connecting all nodes of D. Terminology: The nodes of D are called terminals, the other nodes are called Steiner nodes. Application Example Connecting all components in an printed circuit using minimum cost silver
