Theory of complex systems and cybernetic picture of the world

Any complex system interacts with changing environment and its availability depends on its adaptability. The number of arbitrary coefficients in the structure of equivalent equations of complex system changes in the process of learning. In systems with more then six variables, the number of arbitrary coefficients at first increases, and then, passing through the maximum, begins to decrease. This phenomenon makes it possible to explain the processes of system growth, complication, and death in biological, economical, and physical-engineering systems. The linguo-combinatorial method of complex systems investigation is used, key words being taken for building equivalent equations.
