Yas Marina Circuit circuit bosses and Formula One drivers for the high level of grip it offers. The same aggregate material is used at the Bahrain International Circuit for the Bahrain Grand Prix. On 7 October 2009, the circuit was granted final approval to hold Formula One races by the FIA. Bruno Senna was the first driver to complete a test run on the circuit. GP3 visited Abu Dhabi for the first time at the end of the 2013 season. After the first practice sessions at the 2009 Abu Dhabi Grand Prix, the circuit was welcomed by the drivers, with Nico Rosberg commenting
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
