Active today. It only takes a minute to sign up. What does it mean when an aircraft is statically stable but dynamically unstable? In other cases, it is more natural to associate with each connection some numerical "weight". Details. An unweighted graph is one in which an edge does not have any cost or weight associated with it, whereas a weighted graph does. Following is an example undirected and unweighted graph with 5 vertices. Each edge of a graph has an associated numerical value, called a weight. and a particular edge {u, v} in the graph.
