It is a solution concept based on how players think about other players' thought processes.
A solution concept is a vector that represents the allocation to each player.
Some properties to look for in a solution concept include:
Uniqueness: The solution concept is unique for any game .
This and other difficulties have led to the development of many other solution concepts.
The solution concept represents technical realization that satisfies at least the required performance.
Design decision is a development of a solution concept.
The Nash equilibrium is the traditional solution concept in game theory.
These "solution concepts" are usually based on what is required by norms of rationality.
In game theory, a solution concept is a formal rule for predicting how a game will be played.
