Yas Island development. Yas Island holds the Yas Marina Circuit, which has hosted the Formula One Etihad Airways Abu Dhabi Grand Prix since 2009. Both business and leisure travelers visit Yas Island. Yas Island was named the world's leading tourism project at the World Travel Awards in November 2009. The Park’s foundation stone was laid on 3 November 2007. The development was completed in a little under three years, opening to the public for the first time on November 2010. Formula Rossa, one of the park's most famous attractions, is the world’s fastest rollercoaster reaching a speed of 240 kph (149 mph).
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
