Abstract
The concept of a "strategy" is one of the chief concepts of the game theory, which is currently enjoying wide popularity in a number of sciences, including psychology, particularly in connection with the study of problem solving. However, since no clear-cut definition of this concept exists, we start with the most general working definition of the term, in which strategy is understood to refer to some more or less definite course of search, that is, to the tendency to adhere to one specific method in solving any given problem.
