WebMoreover, we derive the Pareto-optimality condition for distributed policies that balance the variance and mean square of the service capacity. Finally, we discuss a scalable partially centralized algorithm that uses centralized information to boost performance and a method to deal with missing information on service requirements.

WebIn case we have detected optimality we will extract the potential minimizers with a truncated version of the Gelfand–Naimark–Segal construction on the optimal solution of the Lasserre relaxation. We prove also that the operators of this truncated construction commute if and only if the matrix of this modified optimal solution is a generalized Hankel matrix.

WebIn works devoted to the universe, the optimality of its evolution is noted. However, specific mathematical models, according to which the evolution of the universe takes place, are not given in them (see, e.g. [1] ). In the book [2] , instead of the optimality of the evolution of the Universe, the term “cosmic wisdom” is applied.
