Circuit rank of any planar graph with the same vertex set, is called the meshedness coefficient. For a connected planar graph with edges and vertices, the meshedness coefficient can be computed by the formula Here, the numerator formula_5 of the formula is the circuit rank of the given graph, and the denominator formula_6 is the largest possible circuit rank of an -vertex planar graph. The meshedness coefficient ranges between 0 for trees and 1 for maximal planar graphs. The circuit rank controls the number of ears in an ear decomposition of a graph, a partition of the edges of the graph into
