In 1928 John von Neumann proved the fundamental statement about the existence of a balance point in a two-person zero-sum game. In 1994, this result, generalized by John Nash in 1951 was awarded the Nobel prize. The basic idea formulated by von Neumann comes down to the expansion of the set of decisions which in the theory of games are frequently known as strategies. Convex combinations of pure strategies i.e. mixed strategies, are examined in place of pure strategies. The idea of averaging, of course, is quite old. It is familiar to every gardener who by diversifying the species of trees in his orchard safeguards it against bad harvest, ill weather and pests. Variety renders the set stable and guarantees a steady balance. An energy system with one large power plant is unstable while an analogous system composed of 100 smaller plants, combined into a single network, is extremely stable although its effectiveness could be slightly lower. The problem of diversification occurs in production - it is easier to sell numerous products than a single one; it also takes place in insurance and in the purchase of shares on the exchange. The leitmotif of Japanese operational groups in assorted enterprises - keiretsu -is also diversification, since variety always increases security. The most diversified of all is nature. The great number of assorted species stabilizes the organic world and ensures its survival in unfavorable conditions. An excellent example of the positive impact of diversification is the universally recognized phenomenon known a the Coolidge effect. This study distinguishes two meanings of the term diversification. The basic meaning corresponds to the convex combination of vectors, and the second is connected with reliability. The diversification of the structure of the cybernetic set depends of the values assumed by the function of reliability. (original abstract)
