0 a mathematical theory about how decisions are made in situations where one person's decision affects another, that is used in many fields such as economics, psychology, and biology --
1 an economic theory that tries to calculate what choices people will make, when those choices depend on the choices of others: --
Some of the most interesting ideas are coming from game theory, the field of mathematics that studies strategic behaviour in competitive situations.
There is no reason to denigrate the contributions of coalitional game theory, either on the applied or the theoretical level.
Broadly, these split into two groups- those which focused on game theory and those which focussed on decision theory.
In applications of game theory in multi-agent systems, agents are usually taken to maximise their expected utility.
In this case, most authors38-41 suggest the use of methods from the game theory.
Nevertheless, the assumption is well accepted in non-cooperative game theory, so much so that it is hard to encounter justifications for it.
We re-examine this theory by reconstructing key parts in a more formal way, extending it, and showing how it differs from more recent game theory.
His research focuses on social choice theory and on cooperative game theory.
Part of the problem is that game theory has used lots of applied math and little empirical observation.
