Boundedness and Self-Organized Semantics: on the Best Survvival Strategy   in an Ever-Changing Environment
  General criterion for best efficiency of the interaction of a complex system with an ever-changing environment is derived. Its exclusive property, set by boundedness, is that the highly non-trivial interplay between parameters that participate in it renders the best survival strategy to go via non-extensive hierarchical super-structuring of the semantic-like response.
