👉 In mathematics, a nodulate function is a special kind of function that maps two sets into one. A nodulate function is often used in combinatorics and graph theory to describe certain types of connections between graphs or networks. A node in a graph is a vertex with no edges connected to it. When we talk about nodulation, we are looking at how the nodes in a graph can be connected to each other using an edge. The process by which these edges are created depends on the specific
