Markov models of macrosystems
  We collect different examples reflect Bolzman--Jaynes theory of maximum entropy principle. This principle proposed that equillibrium of macrosystem (most probable macrostate of the invariant measure of macrosystem) can be find as a solution of the entropy linear programming problem. Among this examples one can find applications to the economics, sociology, linguistics, traffic flow theory, biology e.t.c. We also describe on examples the connection between Nash's equillibrium, Darwin's principle of natural selection and conception of equillibrium of macrosystem.
