Lecture 7: Minimum Spanning Trees and Prim’s Algorithm

WebGeneric approach: A tree is an acyclic graph. The idea is to start with an empty graph and try to add edges one at a time, always making sure that what is built remainsacyclic. And if we are sure every time the resulting graph always is a subset of some minimum spanning tree, we are done. 7 WebThreshold graphs are a well-studied graph class with a variety of the-oretical applications [18], and they are both split graphs and interval graphs [5, 12].
