“Non-Cooperative Games”, 1951-09-01 (; backlinks; similar):
…Our game theory, in contradistinction, is based on the absence of coalitions in that it is assumed that each participant acts independently, without collaboration or communication with any of the others.
The notion of an equilibrium point is the basic ingredient in our theory. This notion yields a generalization of the concept of the solution of a 2-person zero-sum game. It turns out that the set of equilibrium points of a 2-person zero-sum game is simply the set of all pairs of opposing ‘good strategies’.
In the immediately following sections we shall define equilibrium points and prove that a finite non-cooperative game always has at least one equilibrium point. We shall also introduce the notions of solvability and strong solvability of a non-cooperative game and prove a theorem on the geometrical structure of the set of equilibrium points of a solvable game.
As an example of the application of our theory we include a solution of a simplified 3 person poker game.
