  Well, thank you. Actually it's possible to follow even for someone without CS education like me. I have skimmed over it and actually it seems that although they are confident that the string rewriting system is equivalent to the conjecture it has not been proven yet. Anyway it's very interesting, I will try to read it in depth.
