The P-NP problem is the most important open problem in computer science, if not all of mathematics. Simply stated, it asks whether every problem whose solution can be quickly checked by computer can also be quickly solved by computer. The Golden Ticket provides a nontechnical introduction to P-NP, its rich history, and its algorithmic implications "Accessible and easy to digest. . . . The Golden Ticket is a great introduction to a maths problem that few people know about and even fewer understand and a great way to try to start thinking about it and its implications."---Johar M. Ashfaque, Mathematics Today
