N. KASKOV "demonstrated that the following mass problems could not be solved in the framework of the General System Theory:

- to construe an algorithm allowing to find all the elements of a given system

- to construe an algorithm allowing to find all the connections of a given system

- to construe an algorithm allowing to determine the structure of a given system

- to construe an algorithm allowing to determine all the functions realized by any given system (even if one knows its elements, connections and structures)" (BLAUBERG, SADOVSKY & YUDIN, 1977, p.205)

Any complex system seems to contain a power for innovative and unpredictable variations, due probably to its relatively open character.
