We're excited to announce that the $25,000 Wolfram 2,3 Turing Machine Research Prize has been won.

Alex Smith, a 20-year-old undergraduate in Birmingham, UK, has given a 40-page proof that Wolfram's 2,3 Turing machine is indeed universal.

This result ends a half-century quest to find the simplest possible universal Turing machine.

It also provides strong further evidence for Wolfram's Principle of Computational Equivalence.

The official prize ceremony is planned for November at Bletchley Park, UK, site of Alan Turing's wartime work.

Stephen Wolfram has posted his personal reaction to the prize at:

I am still reading the biography of Alan Turing. I am reading chapter 6 now. World war II has ended and Alan is writing a proposal to get a project for building a general purpose computer ( the first one ever ) funded. He wrote his paper on the Universal Turing Machine long before the war started.
