For others, a pseudograph is a multigraph that is permitted to have loops multiple edges connecting the same pair of vertices or a vertex to itself, are sometimes called pseudographs. I have a multigraph object and would like to convert it to a simple graph object with weighted edges. Multigraph definition is - a machine consisting essentially of a cylinder with grooves into which type or electrotypes are inserted —formerly a U.S. registered trademark. A graph in which loops and multiple edges are allowed is called psuedograph. Multigraph are graph having parallel edges depicting different types of relations in a network. Example- Here, This graph consists only of the vertices and there are no edges in it. If a pair of vertices is joined by more than one edge, the edge is called a multiple edge, and the graph is called a multigraph. There are no parallel edges but a self loop is present.

If in a graph multiple edges between the same set of vertices are allowed, it is called Multigraph. A graph g= (V, E) is said to be a multigraph in case there are multiple edges exist between a pair of vertices in the graph. A graph G= (V, E) is said to pseudo graph in case it contains a self-loop along with other edges. What is the difference between a generative and a discriminative algorithm?
