Application: Process Relations

Application: Process Relations. Some algorithms require that sub processes (tasks) are executed in a certain order, because they use data from each other Example: get dressed In which order should I don my clothes? ? Such an order is known as a topological sort. Tee-shirt before shirt

Minimum Spanning Tree

Minimum Spanning Tree. Spanning Trees. A spanning tree of a graph is just a subgraph that contains all the vertices and is a tree. A graph may have many spanning trees. Spanning trees are defined for connected undirected graphs Since there are trees ? They have no cycles. Graph A.

Minimum Spanning Trees

Minimum Spanning Trees. Section 8.3. Definition. For a undirected graph G=(V,E), a spanning tree T is a sub-graph that is a tree covering all vertices in V. In an undirected weighted, a Minimum Spanning Tree (MST) is the spanning tree with the min sum of weights.
