How to know the discriminant of a graph?

If you see the discriminant of a graph, you can know whether the graph is simple or not. You can also check the isomorphism between graphs using the discriminant of the graphs. Graph discriminant is also an important tool for solving the graph isomorphism problem. Graph isomorphism is the problem to determine whether two graphs are isomorphic. If the discriminant of two graphs are equal, it means that they are isomorphic.

How to know the discriminant of a multivariate graph?

A discriminant of a graph is the determinant of its Laplacian matrix. The Laplacian of a graph is a square matrix whose rows and columns are lists of vertex degrees, except for the first column and last row, which consist of the sums of the row and column sums of the first and last vertex degree lists. The graph Laplacian is an effective way to find out whether a graph is regular or not and to calculate other properties of graphs. The discriminant

How to know the discriminant of a multivariate graph in R?

The graph discriminant is the value of the most discriminant variable. Finding the discriminant of a multivariate graph is much more complicated than for the graph. We have to use a function provided in the ‘dmd’ package. The function performs the following operations: it sums the values of the squares of the differences between the means of the groups and the sum of the squares of the means of all the variables in the data. To find the discriminant, we need the function to

How to know the discrimination of a graph?

If you know the degree of each vertex in a graph, you can use the discriminant of a graph to measure how well connected it is. A simple example of a graph whose discriminant is easy to calculate is a star graph. If you have a star graph with five nodes, you can easily check that each vertex has a degree of five. The star graph’s discriminant is equal to -1.

How to know the discriminant of a graph in R?

The discriminant of a graph is the product of the number of vertices and the number of edges. If the discriminant is 0, the graph has a symmetry (isotropy) and has no edges or vertices. This is the case of a single point.
