Circuit Gilles Villeneuve from the 2009 Formula One calendar and replaced with the inaugural Abu Dhabi Grand Prix. On November 27, 2009, Quebec's officials and Canadian Grand Prix organizers announced a settlement with Formula One Administration and signed a new five-year contract spanning the 2010–2014 seasons. The 2011 edition took place on June 12 at 1:00 pm (17:00 UTC) and was the longest World Championship Grand Prix ever, due to a lengthy rain delay. Originally named the Île Notre-Dame Circuit, the circuit was built and finished in 1978. In what has proven to be the venue's main event over the decades, the FIA
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
