As Fortnow describes. . . P versus NP is one of the great open problems in all of mathematics' not only because it is extremely difficult to solve but because it has such obvious practical applications. It is the dream of total ease, of the confidence that there is an efficient way to calculate nearly everything, from cures to deadly diseases to the nature of the universe,' even an algorithmic process to recognize greatness.'. . . To postulate that P NP, as Fortnow does, is to allow for a world of mystery, difficulty, and frustration--but also of discovery and inquiry, of pleasures pleasingly delayed.--Alexander Nazaryan, New Yorker ukryj opis
