Degree of Order Criteria of the Elements’ Deterministic Chains With Relations Between the Closest Neighbors

V. I. Ilyevsky · Journal of Advances in Mathematics and Computer Science · 2014

For the first time ever, this work formulates definition of the degree of order for the non-random sequence of elements. Earlier, the only known parameter to evaluate a system’s degree of order was entropy. It has been shown that using entropy to evaluate the degree of order in d...
