Road Coloring Problem Solved 202
ArieKremen writes "Israeli Avraham Trakhtman, a Russian immigrant mathematician who had been employed as a night watchman, has solved the Road Coloring problem. First posed in 1970 by Benjamin Weiss and Roy Adler, the problem posits that given a finite number of roads, one should be able to draw a map, coded in various colors, that leads to a certain destination regardless of the point of origin. The 63-year-old Trakhtman jotted down the solution in pencil in 8 pages. The problem has real-world implementation in message and traffic routing."

2) I read the linked-to blurb(s)* and promptly got confused. I'm sure this is indeed some sort of breakthrough, but could some of the more mathematically-literate Slashdotters out there translate this into an explanation that the rest of us could understand? I'd particularly like to see exactly how this finding applies to real-world applications. Thanks in advance...
