👉 A nodosity is a mathematical concept in mathematics, specifically in combinatorial analysis and graph theory. It refers to the number of edges that need to be removed from a complete graph (a graph with no self-loops) to make it a tree or a forest. In other words, a nodosity is the minimum number of edges required to remove so that the resulting graph becomes connected. Nodosities are important in graph theory because they provide an upper bound on the maximum size of
