Travelling Salesman (2012)
Travelling Salesman is a 2012 intellectual thriller film about four mathematicians solving the P versus NP problem, one of the most challenging mathematical problems in history. The title refers to the Travelling salesman problem, an optimization problem that acts like a key to solving other mathematical problems that are thought to be hard. By solving the Travelling salesman problem quickly the mathematicians can, for example, also factor large numbers quickly. Since many cryptographic schemes rely on the difficulty of factoring integers to protect their data this would allow access to private data like personal correspondence, bank accounts and possibly government secrets.
