Spanning trees
from class: Math for Non-Math Majors Definition A spanning tree is a subgraph of a connected, undirected graph that includes all the vertices with the minimum possible number of edges. It contains no cycles and connects all the vertices together.
congrats on reading the definition of spanning trees . now let's actually learn it.
Predict what's on your test 5 Must Know Facts For Your Next Test A spanning tree for a graph with \(n\) vertices has exactly \(n-1\) edges. There can be multiple spanning trees for a single graph. Removing any edge from a spanning tree will disconnect it. The Minimum Spanning Tree (MST) is a type of spanning tree that minimizes the total edge weight. Kruskal's and Prim's algorithms are commonly used to find Minimum Spanning Trees. Review Questions What is the relationship between the number of vertices and edges in a spanning tree? How does removing an edge from a spanning tree affect its structure? What algorithms can be used to find a Minimum Spanning Tree? "Spanning trees" also found in:
