Initially it was developed to analyze competitions in which one individual does better at another's expense: zero sum games (Morgenstern, & von Neumann, 1947). From that moment, traditional applications of game theory attempt to find equilibria in these games. In any equilibrium each player of the game adopts a strategy that they are unlikely to change. Many equilibrium concepts have been developed; among them we find the famous Nash equilibrium, in an attempt to capture this idea (Nash, 1950). Game theory was developed extensively in the 1950s by many scholars and it was later explicitly applied to biology from the 1970s (Maynard Smith, 1982), although similar developments go back at least as far as the 1930s (Fisher, 1930)
