About expert information

Introduction. The actual task of materials science is a functional description of the material quality criteria based on the analysis of the influence of structure elements. This task is due to the difficulties in determining the metrics for the identification object in the state space. Main part. Ways of solving the problem of identifying metal quality criteria using expert systems of a certain class are considered. Thus the known problems of nonlinear dynamics and their communication with the hypothesis Wallfrem about numerical irreducible algorithms and the theorem Takens about existence of functional communication between the current and previous results of measurements are taken into account. Conclusions. Thus, the ways of identification of computationally irreducible systems by applying expert in-formation are shown.
