WebIn this lecture we give an algorithm for Steiner tree and then discuss greedy algorithms. 2.1 Steiner Tree Problem Statement: Given a weighted graph G = (V,E) and a set R ⊆ V, our goal is to determine the least cost connected subgraph spanning R. Vertices in R are called terminal nodes and those in V\R are called Steiner vertices. WebFull binary tree, seven vertices, of which four are internal vertices 7. Full binary tree, twelve vertices 8. Full binary tree, nine vertices 9. Binary tree, height 3, seven terminal vertices …
