What is the maximum number of edges in a graph with 10 vertices?
What is the maximum number of edges in a bipartite graph having 10 vertices? Explanation: Let one set have n vertices another set would contain 10-n vertices. Total number of edges would be n*(10-n), differentiating with respect to n, would yield the answer. 11.
What is the maximum number of edges in a graph on 10 vertices with no triangles?
The basic statement of extremal graph theory is Mantel’s theorem, proved in 1907, which states that any graph on n vertices with no triangle contains at most n2/4 edges.
What is the minimum and maximum number of edges in a simple graph of n vertices?
A graph with no loops and no parallel edges is called a simple graph. The maximum number of edges possible in a single graph with ‘n’ vertices is nC2 where nC2 = n(n – 1)/2. The number of simple graphs possible with ‘n’ vertices = 2nc2 = 2n(n-1)/2.
How many edges does a tree with 10 vertices have?
A connected acyclic graph is a tree. A tree with n vertices has n−1 edges. Hence there are no connected acyclic graphs with 10 vertices and 10 edges.
What is the maximum number of edges in a bipartite graph having 20?
Is it true that every complete bipartite graph is a modular graph. Consider a complete graph G with 4 vertices….

What is the maximum number of edges in a bipartite graph having 10 vertices 26 25 24 23?
This has 25 edges, because the number of edges is the product of the number of vertices on each side.
What is the maximum number of edges in a graph with n vertices?
In a directed graph having N vertices, each vertex can connect to N-1 other vertices in the graph(Assuming, no self loop). Hence, the total number of edges can be are N(N-1). There can be as many as n(n-1)/2 edges in the graph if not multi-edge is allowed.
What is the maximum number of edges?
The maximum number of edges in an undirected graph is n(n-1)/2 and obviously in a directed graph there are twice as many. If the graph is not a multi graph then it is clearly n * (n – 1), as each node can at most have edges to every other node.
How many edges can a simple graph have?
A simple graph is a graph that does not have more than one edge between any two vertices and no edge starts and ends at the same vertex. In other words a simple graph is a graph without loops and multiple edges. Two vertices are said to be adjacent if there is an edge (arc) connecting them.
How do you calculate the edge of a tree?
Circuit Rank A spanning tree ‘T’ of G contains (n-1) edges. Therefore, the number of edges you need to delete from ‘G’ in order to get a spanning tree = m-(n-1), which is called the circuit rank of G. This formula is true, because in a spanning tree you need to have ‘n-1’ edges.
