Lin An woke up and found himself in an Eastern Fantasy world. In this world, power was everything. The powerhouses could easily control it all. Those who were capable enough could claim everything, be it money, women, or power. A voice sounded in the mind of Lin An, who was still puzzled over his reincarnation to the Eastern Fantasy World. [Congratulations, host! You have activated the Success Rate System. Whatever you do, you will be able to see your success rate!] Since then, Lin An was able to check his success rate every time before he did something! “The chances of you successfully refining your body with this body refining technique are 90%.” “The chances of you obtaining treasures when you open this treasure box are 100%.” “The chances of you surviving in this cave are 0%.” “The chances of you being favored by the sacred maiden and having a relationship with her are 100%.”
e of a problem that we don’t know how to solve in polynomial time. In this problem, the input is a boolean circuit: a collection of and, or, and not gates connected by wires. We will assume that there are no loo** in the circuit (so no delay lines or flip-flo**). The input to the circuit is a set of m boolean (true/false) values x1, . . . , xm. The output is a single boolean value. Given specific input values, we can calculate the output in polynomial (actually, linear ) time using depth-first-search and evaluating the output of each gate in constant time. The circuit satisfiability problem asks, given a circuit, whether there is an input that makes the circuit output True, or conversely, whether the circuit always outputs False. Nobody knows how to solve this problem faster than just trying all 2 m possible inp
