What is a rooted tree in graph theory?
A tree in which one vertex called the root, is distinguished from all the others is called a rooted tree.
In graph theory does a point have size?
No.
What is a cycle in graph theory?
If the graph start and end with same vertex and no other vertex can be repeated then it is called trivial graph.
When does a graph becomes a tree?
A graph becomes a tree when it is connected and acyclic, meaning there are no loops or cycles present. Additionally, for a graph with ( n ) vertices to be a tree, it must contain exactly ( n-1 ) edges. This structure ensures that there is exactly one path between any two vertices, fulfilling the properties of a tree.
Prove that a graph G is connected and only if it has a spanning tree?
Proving this is simple. First, you prove that G has a spanning tree, it is connected, which is pretty obvious - a spanning tree itself is already a connected graph on the vertex set V(G), thus G which contains it as a spanning sub graph is obviously also connected. Second, you prove that if G is connected, it has a spanning tree. If G is a tree itself, then it must "contain" a spanning tree. If G is connected and not a tree, then it must have at least one cycle. I don't know if you know this or not, but there is a theorem stating that an edge is a cut-edge if and only if it is on no cycle (a cut-edge is an edge such that if you take it out, the graph becomes disconnected). Thus, you can just keep taking out edges from cycles in G until all that is left are cut-gees. Since you did not take out any cut-edges, the graph is still connected; since all that is left are cut-edges, there are no cycles. A connected graph with no cycles is a tree. Thus, G contains a spanning tree. Therefore, a graph G is connected if and only if it has a spanning tree!
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 spaning tree in c programming?
Nothing, but it has significance in graph-theory.
What is a rooted tree in graph theory?
A tree in which one vertex called the root, is distinguished from all the others is called a rooted tree.

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.
Is every tree a graph or every graph a tree?
true
Is every tree a bipartite graph?
Yes, every tree ia a bipartite graph (just see wikipedia).
When was Journal of Graph Theory created?
Journal of Graph Theory was created in 1977.
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?
Every tree is a connected directed acylic 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.
