The article presents the basic concepts and reviews the main results of the theory of optimal algorithms and informational complexity. Informational complexity bounds are provided for Lipschitzian multi-criterion problems that construct the approximate Pareto-optimal strategy set under different interpretations of approximation-approximation ``by the functional'' and approximation ``by the argument.'' The informational complexity is compared for the scalar global optimization problem and the problem of finding the roots of nonlinear equations by global search methods.
