It's ok. I'm done looking - I can see why you were having trouble though: The search algorithm you provided me with does not have sufficient inputs to match the limitations of the search interfaces [arxiv and google scholar] . smile emoticon It's the same trouble with a lot of paradoxes: Most are easily resolved but you have to step outside of the constraints of the system to resolve them, which is usually unsatisfactory but practical. I solved an ancient logic paradox today easily. "Barber Paradox". It's missing one input. Time. Then you can resolve it. But by doing that, it ceases being a logic problem and becomes a program smile emoticon Resolved? yes, but outside of the constraints of the system required by Logic, which is that it must be evaluated "at once" and not over a period of time or with additional conditionals. Oh well smile emoticon Sorry I couldn't help!
