(2020) and proper characterization, complexity does not decrease.

It finds this view is an artifact of how systems are characterized by dimension and resolution.\\n\\nCore result: when natural patterns are measured with a multi-scale complexity metric from Bagrov et al. (2020) and proper characterization, complexity does not decrease. It aligns statistically with thermodynamic entropy.\\n\\n## Exact primary works and passages\\nThe paper is Wang, H., Song, C., & Gao, P. (2024). Complexity and entropy of natural patterns.
