A matching, also called an independent edge set, on a graph is
a set of edges of
.
such that no two sets share a vertex in common
. It is not possible for a matching on a graph with nodes to exceed edges.
What is matching and comparing?
For example, a kid puts two toys together as they look the same and have both yellow colors or puts two books in the same bookshelf because they have the same size and look the same. Comparing means
looking at two objects and finding their similarities and differences

Matching is
the process in which we connect any two similar objects which are given in two different sets
. When more than two objects are grouped together based on a common characteristic, it is known as sorting.
What is matching in a graph?
Given an undirected graph, a matching is a set of edges, such that no two edges share the same vertex. In other words, matching of a graph is
a subgraph where each node of the subgraph has either zero or one edge incident to it
. A vertex is said to be matched if an edge is incident to it, free otherwise.
How do you teach matching skills?

picture of the desk
and match it to a desk in the classroom, and the picture of a book and match it to a book on the shelf. A more advanced activity is to match words to objects.
Does every graph have a matching?

every perfect matching is a maximum independent edge set
.
What means matching with?

to examine the differences between numbers, quantities or values to decide if it is greater than, smaller than or equal to another quantity

Is a perfect matching a maximum matching?
A perfect matching is a matching that matches all vertices of the graph. That is, a matching is perfect if every vertex of the graph is incident to an edge of the matching.
Every perfect matching is maximum
and hence maximal.
