Аннотация:We state a tree labeling problem, give an algorithm for solving it, and discuss some complexity characteristics of the algorithm. Furthermore, we discuss applications of these results to the approximation of a continuous function with given accuracy by linear combinations of characteristic functions of dyadic intervals with as few summands as possible. We also touch upon issues concerning tree-aided signal discretization.
