We're very excited to be hosting the UK premiere of acclaimed indie film Travelling Salesman, a mathematical thriller imagining the consequences of solving the P vs NP problem.

Travelling Salesman is an intellectual thriller set in a fictional reality where four brilliant mathematicians solve the P vs NP problem, one of the hardest open problems in maths with profound implications for computer science and cryptography. Offered $10 million dollars by the US government for exclusive access to the solution, they must grapple with the practical and moral repercussions of discovering a proof that P = NP. (Find out more about the P vs NP problem here.)

This is the first time that Travelling Salesman has been shown in the UK. The screening will be prefaced by a short introductory talk by Professor Jonathan Oppenheim (UCL) and will be followed by a live Q&A session with the writer/director, Timothy Lanzone.

Entry is by ticket only (£7.50 each - please note the event is now sold out). The event will start at 6.30 pm, and should finish by 8.30/8.45pm.

See the official Travelling Salesman website.

"It is not often that espionage thrillers feature a round of peer review, but this early scene is a natural fit for Travelling Salesman, a film based on the premise that the biggest unsolved problem in computer science has been cracked. ... P = NP ... is a great premise that writers Andy and Timothy Lanzone use to explore the theme of scientific hubris. Travelling Salesman’s mathematicians are all too aware of what their work will do to the world, and watching them argue how to handle the consequences offers a thriller far more cerebral than most."
