The method of partial approximation in the problem of finding informative parts of experimental curves

The problem of identifying informative intervals is formulated in computer analysis of complex experimental curves. These intervals are informative which are a stronger hindrance for the curve to be approximated by a polynomial in a certain linearly independent system to functions. A functional is constructed which is defined on a set of subsets of a specified length inside the range where the curve can be determined; an iterative algorithms for minimization of the functional is also desogned.
