	Book review: Non zero (Site not responding. Last check: 2007-10-03)
		Non zero by Robert Wright (bearing the somewhat grandiose subtitle “The logic of human destiny”) is one of the most interesting books I’ve ever read, AND it tackles two of those questions in a thorough and readable way.
		A zero sum game is one in which I have to loose in order for you to win.
		One again, non zero cooperation can be seen as the driving force, and can be the explanation for many of symbiotic relations we see.

	Making Games Zero Sum
		If the sum of all the scores of all the players is zero, and there is only one player, then his score will be zero too.
		A basic theorem of game theory says that an n player non-zero sum game is equivalent to a n+1 player zero sum game, where the new player gets the negative of the sum of scores of the other players.
		The first case could be called a zero sum two player game, and the second case a one player non-zero sum game.

		Non Zero Sum is a progressive-rock band from Seattle, Washington.
		Although the members of Non Zero Sum were raised in musical environments and discovered their talents young, it wouldn't be until 1998 when Joel Johns, Ryan Summers, and Jeff Johns started jamming; then decided to form a band.
		Many fans have compared Non Zero Sum's sound to such artists as their music appeals to such a wide variety of musical tastes; yet it remains to be most unlike anything out there.

		While infinite "zero sum" games (where two players have directly conflicting objectives) have been studied extensively in verification and automata theory, "non-zero sum" games (where each player has his/her own objective) have not.
		For zero sum games, the fundamental solution concept is determinacy: to show that the value of player 1 is one minus the value of player 2.
		For non-zero sum games, Sudderth and Secchi showed the existence of Nash equilibria in safety games, however, not much more is known.

	Book review of Robert Wright
		Wright claims that this is a consequence of the mathematics of non-zero sum games: over the long run, the outcome of non-zero sum games tends to be more positive than negative.
		He even seems to think that this new system (the medieval system of city-states) is an example of non-zero sum game (cooperation) instead of zero-sum game (competition), and the Roman Empire was the opposite, a reversal of their intuitive roles which is truly hard to understand.
		On the contrary, it seems to this reader that the Roman Empire was one of the best examples of cooperation (non-zero sumness) and its disintegration led to an age of competition (zero zumness) among the former pieces of it.

	Game Theory
		Chess is another zero sum game, because the number of chess pieces available never goes up.
		There are six possible non redundant outcomes, all of which can be oriented or reflected 8 different ways, for a total of 48 possible rational outcomes of tic-tac-toe, all of them draws.
		Non-zero sum games means that both players could potentially gain or lose based on their strategy.

	Zero-Sum
		If there is even one strategy set for which the sum differs from zero, then the game is not zero sum.
		SOLUTION: Maximin criterion For a two-person, zero sum game it is rational for each player to choose the strategy that maximizes the minimum payoff, and the pair of strategies and payoffs such that each player maximizes her minimum payoff is the "solution to the game."
		The serious interactions are instances of "nonconstant sum games," since the winnings and losses may add up differently depending on the strategies the participants choose.

		In order to gain non-zero sum benefits, trust and communication are necessary, but how one acts towards betrayal is very important.
		Avoiding the cycle of revenge and mistrust that lead to war and other negative sum outcomes is important.
		Nonzero's discussion of iterated prisoners dilemmas, based on Axelrod's work is interesting, in that it explains the advantages of the 'Tit for Tat' strategy, but more recent research shows that more forgiving strategies win out in the long run, especially over generations.

	NonZero
		The “non zero” in the title is a phrase he has borrowed from the branch of mathematics called “game theory” and he uses the term as a convenient catch phrase when talking about cooperation between entities that results in an evolutionary gain.
		This little mind game “the prisoners dilemma” is used by game theory people to explain the difference between what they call zero sum games and non zero sum games “Zero sum” means one winning side and one losing side.
		Non zero sum means at least something is won on both sides.

	GBN: Nonzero
		Mutual self-interest, or what Wright awkwardly calls "non-zero sumness," is the engine steadily marching us toward universal literacy and widespread global trade.
		Wherever there is a chance for non-zero sum outcomes, or win-wins, then civilization advances.
		Wright's iconoclastic view of the world is worth paying attention to because ultimately his notion of progress and civilization comes down to bits—memes migrating from one culture to the next—and if this really is an information age, then non-zero sumness is a simple equation that may unleash great power.

		According to this theory, a conflict situation does not necessarily have to end with winners and losers, a situation described in game playing jargon as a "zero sum game," in the sense that both parties could be winners (a "non-zero sum game plus") or losers (a "non-zero sum game minus").
		For instance, passing from a state of war to a state of peace could be perceived as a "non-zero sum game plus," in which both parties benefit from ending the hostilities and building peace.
		Would this be a "non-zero sum game," with a plus for both parties, or a "zero sum game," where the plus for one party is actually a minus for the other?

		But if the zero sum components are prominent, future interactions may not be likely.
		Wright suggests that it is the accumulation of these non-zero sumness games -- games upon game upon game - that has led to social and biological complexity and progress in humans.
		This non-zero sumness activity emphasizes non-competitive cooperation and collaboration within societies and organizations, and between societies and organizations.

	Zero-sum - Wikipedia, the free encyclopedia
		Chess and Go are examples of a zero-sum game - it is impossible for both players to win.
		Other non-zero-sum games are games in which the sum of gains and losses by the players are always more or less than what they began with.
		For example, a game of poker played in a casino is a zero-sum game unless the pleasure of gambling or the cost of operating a casino is taken into account, making it a non-zero-sum game.

		Nor is it to say that the powerful and the treacherous never exploit the weak and the naïve; parasitic behavior is often possible in non-zero-sum games, and history offers no shortage of examples.
		Still, on balance, over the long run, non-zero-sum situations produce more positive sums than negative sums, more mutual benefit than parasitism.
		This basic sequence -- the conversion of non-zero-sum situations into mostly positive sums -- had started happening at least as early as 15,000 years ago.

	Zero sum stupid
		I expected a total puff answer but was surprised to hear Jobs talk pointedly about the difference between zero sum market places and non-zero sum ones, and specifically talk about the different industry dynamics when you're out choosing an Apple over a Dell (either/or) as opposed to seeing Antz and A Bug's Life.
		According to him, managing a non-zero sum business (including people, projects, strategy, and tactics) was a disaster waiting to happen— which is why this piece in the New Yorker should be required reading for the take-the-market embahs looking for the next eBay opportunity.
		While Surowiecki does not make this same zero-sum argument for why the Nintendo is in a great place with its Wii strategy (he prefers to focus on the classic serving an unserved segment argument), it is nice to see that implicitly the company's strategy is an affirmation of the Jobs statement on competitive dynamics.

		Indeed, even if you start the survey back when the most complex society on earth was a hunter-gatherer village, and follow it up to the present, you can capture history's basic trajectory by reference to a core pattern:
		New technologies arise that permit or encourage new, richer forms of non-zero-sum interaction; then (for intelligible reasons grounded ultimately in human nature) social structures evolve that realize this rich potential--that convert non-zero-sum situations into positive sums.
		Nor is it to say that the powerful and the treacherous never exploit the weak and the naive; parasitic behavior is often possible in non-zero-sum games, and history offers no shortage of examples.

		Wright's aim is to knit together this theory with anthropology, zoology, biology, and history, plus a dash of chaos theory, and thus attest that "non-zero sum altruism" is the natural inclination of humankind.
		To prove this he cites such disparate phenomena as the sago-swapping natives of the US Northwest, the global government-in-waiting that is the European Union, and the anarchically generous ethos that rules the Net--all of which apparently go to show that we are, deep down, caring, sharing nice guys.
		The phrase "zero sum" is in fairly common use in the US, although I have not heard it much in Europe; it means an interaction where there is no overall, net gain for the parties concerned.

		In zero-sum games we needed only one number in each cell because we knew that by the definition of zero-sum, one player won the amount that was in the cell while the other player lost that amount.
		Even though column cares about the second payoff in each cell, the unbolded numbers, column knows that row 2 dominates row 1 and since column prefers 3 to —5, column will pick column 2 and the outcome will be that row wins 12 while column wins 3.

	Slashdot \| Can You Suggest Any Non-Zero Sum Games?
		Zero-sum is a reference to game theory, which holds that any game in which there is one definite winner and one definite loser is a zero sum game: basically, a win is a +1, a loss is a -1, and when you sum the scores, you get zero.
		There are a few examples of non zero-sum games: for example, "The Prisoner's Dilemma" is a non-zero sum game (and technically, it is a game, albeit a very serious one).
		The reason that Zero Sum Games are so popular is that there is a point to them.
