Sport in the United Arab Emirates Dubai Autodrome, opened in 2007, hosted international races in it first years of activity. Its main race is the Dubai 24 Hour endurance race, held since 2009 Abu Dhabi has hosted Formula One races there from the 2009 season onward. The Abu Dhabi Grand Prix is held at the 5.6 km Yas Marina Circuit, located on Yas Island and includes street and marina sections similar to Circuit de Monaco. The UAE hosts Dubai Sevens round of the IRB Sevens World Series. Previously this was held at Dubai Rugby Ground, but from 2008 onwards it has been held at the new
Circuit satisfiability problem finding inputs that make the circuit output 1. (The converse, that SAT is reducible to CircuitSAT, is even easier—we simply rewrite the Boolean formula as a circuit and solve that.) Circuit satisfiability problem In theoretical computer science, the circuit satisfiability problem (also known as CIRCUIT-SAT, CircuitSAT, CSAT, etc.) is the decision problem of determining whether a given Boolean circuit has an assignment of its inputs that makes the output true. CircuitSAT has been proven to be NP-complete. In fact, it is a prototypical NP-complete problem; the Cook–Levin theorem is sometimes proved on CircuitSAT instead of on SAT for Boolean expressions
