There are two players (Players 1 and 2) playing Rock, Paper. Proof: For a zero-sum game, we can use the minimax theorem so that ν({P1}) and ν({P2}) are negative of each other, thus the sum is zero. We will begin by explaining what we mean by rational — or rationalizable — strategies. /FontBBox [-166 -225 1000 931] Modern game theory, the applied math branch established by Neumann & Nash, is the study of mathematical models in conflict & cooperation between intelligent, rational, decision-makers.A tool used in a wide array of industries & fields ranging from economics, to political science, to computer science — the basics of game theory are surprisingly tenable to the average high-schooler. We can see that there is no pure Nash equilibria.
