2011 Formula One World Championship to nineteen races with the postponement and later cancellation of the . The pre-season testing season began immediately after the 2010 Abu Dhabi Grand Prix with a three-day 'Young Driver Test' (for drivers with fewer than three Formula One race starts to their name) at the Yas Marina Circuit. Formula Renault 3.5 runner-up Daniel Ricciardo consistently set the fastest times over the three days, driving for new champions Red Bull Racing. The Young Driver Tests were followed by another testing session – also held at Yas Marina – for the teams to test the tyres developed by new tyre supplier
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
