In graph theory, a tree is a connected, acyclic graph, meaning it has no cycles and there is exactly one path between any two vertices. A tree with ( n ) vertices has exactly ( n - 1 ) edges. Trees are often used to represent hierarchical structures, such as organizational charts or family trees. Additionally, a special type of tree called a "rooted tree" has one designated vertex as the root, from which all other vertices can be reached.

How many nodes are in a family branch tree in graph theory?

In Mathematics and Computer Science, the graph theory is just the theory of graphs basically overall. It's basically the relationship between objects. The nodes are just lines that connects the graph. There are a total of six nodes in a family branch tree for a graph theory basically.

What is the difference between a minimum spanning tree and a shortest path in graph theory?

In graph theory, a minimum spanning tree is a tree that connects all the vertices of a graph with the minimum possible total edge weight, while a shortest path is the path with the minimum total weight between two specific vertices in a graph. In essence, a minimum spanning tree focuses on connecting all vertices with the least total weight, while a shortest path focuses on finding the path with the least weight between two specific vertices.

What is Difference between tree and spanning tree?

A tree is a connected graph in which only 1 path exist between any two vertices of the graph i.e. if the graph has no cycles. A spanning tree of a connected graph G is a tree which includes all the vertices of the graph G.There can be more than one spanning tree for a connected graph G.


Is tree a connected acyclic graph?

What is krushkal algorithm?

Kruskal's algorithm is an algorithm in graph theory that finds a minimum spanning tree for a connected weighted graph. This means it finds a subset of the edges that forms a tree that includes every vertex, where the total weight of all the edges in the tree is minimized. If the graph is not connected, then it finds a minimum spanning forest (a minimum spanning tree for each connected component). Kruskal's algorithm is an example of a greedy algorithm.
