    How can a set of computers agree with eachother if the set size is even or odd?

    I'm not sure how to prove it, but I think that to solve this reliably is an NP-Complete problem and practically is useful for new kinds of routing protocols and a foundation for decentralized global democracy more similar to how Wikipedia allows billions of people to agree on many things instead of top down ways of organizing things.

    How can a set of computers agree with eachother if the set size is even or odd? How do you scale this up?

    In the university-approved textbook of Java programming, I found the problem of 5 people eating with 5 knives and forks positioned between them, at the same round table. I skipped the problem believing that it was easy. Its about threads and concurrent computation.

    Hey Ben, how about a system that is fully interlinked: in such system, there can be odd or even number of links that project from a node to other nodes, but they don't make a difference. Up scaling also reduces the difference between the two halves, odd and even. As long as the symmetry does not play a big role in synchronization, its good. How about it?

    I think I had the same book in college.

    I'm not sure how to explain it. I'm trying to get at the definition of a computer kind of like Godel did, or you can view a set of computers as parts of any Turing Complete cellular automata like Conway's Game Of Life or Rule 110, and the question would be about counting the parts of that automata while its computing.

    "Counting its own parts" would be an interesting search query. I hope that you don't get the Serbian parliament from some 10 years ago, checking manually who is inside, because its like a work of a magician hiding the girl in the box. Very interesting, Ben :-)
