摘要
We review several 統計 complexity measures proposed over the last decade and a half as general indicators of structure or correlation. Recently, Lopez-Ruiz, Mancini, and Calbet [Phys. Lett, A 209 (1995) 321] introduced another measure of 統計 complexity C-LMC that, like others, satisfies the "boundary conditions" of vanishing in the extreme ordered and disordered limits. We examine some properties of C-LMC and find that it is neither an intensive nor an extensive 熱力學 variable and that it vanishes exponentially in the 熱力學 limit for all one-dimensional finite-range spin systems. We propose a simple alteration of C-LMC that renders it extensive. However, this remedy results in a quantity that is a trivial function of the 熵 density and hence of no use as a measure of structure or memory. We conclu
