The example of a game with no core is not very clear. I think it would be a good idea to spell out why there is no solution for 3 miners which cannot be improved for some coalition. Something along the lines of "If there are 3 miners, A, B, and C, and A and B choose to split all the gold between them, then C could offer A a split that is not 50/50. In order for this to be an improvement, C would be getting some non-zero amount and A would be getting the rest, meaning that B could always team up with C to split 50/50 again. So since any payout besides (1/2, 1/2, 0) leaves 2 miners that are getting less than 1/2 (and would thus benefit from a 50/50 split), and the payout of (1/2, 1/2, 0) can be improved by the miner getting 0 offering a non-50/50 split to one of the others, no payout is core."

[edit] Economics or game theory?
I consider core a game theoretic concept so I am a bit puzzled by the lack of game theory on this page. After a quick survey among colleagues I am rather sure that although core-related results existed in the literature prior to Gillies, these have been rediscovered and labelled as "core" later. If no-one objects I will update the page accordingly.Koczy 17:52, 3 August 2007 (UTC)
