Any of you ever hear of this? I caught this on Digg and was fascinated!
63-year-old solves riddle from 1970
I wish I knew more about the Road Coloring Problem. I looked on Wikipedia and there is an article, but not being a mathematician, it went over my head.A mathematical puzzle that baffled the top minds in the esoteric field of symbolic dynamics for nearly four decades has been cracked — by a 63-year-old immigrant who once had to work as a security guard.
The conjecture essentially assumed it's possible to create a "universal map" that can direct people to arrive at a certain destination, at the same time, regardless of starting point. Experts say the proposition could have real-life applications in mapping and computer science.
Any of you know how the solution to the problem might have applications to mapping?In the real world, this phenomenon would be as if you called a friend to ask for directions to his house, and he gave you a set of directions that worked no matter where you started from.
