PPT-Lecture 6A – Introduction to Trees & Optimality Criteria

Branches n taxa gt 2 n 3 branches 1 2 4 6 amp 7 are external leaves 3 amp 5 are internal branches edges Nodes A E are terminals x y amp z are internal vertices . Trees are a specific instance of a construct called a graph In general a graph is composed of edges and vertice s that link the nodes together A graph G is often denoted GVE where V is the set of vertices and E the set of edges Two types of graphs Introduction Composite MaterialsStructures NachiketaTiwari Nachiketa Tiwari InstituteTechnologyKanpur Lecture HygroscopicStressesPlates LectureOverview Lecture Overview Introduction MechanicalHygrosco R.
