  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.
