  "Description": "Main functionality is to provide the algorithmic\ncomplexity for short strings, an approximation of the\nKolmogorov Complexity of a short string using the coding\ntheorem method (see ?acss). The database containing the\ncomplexity is provided in the data only package acss.data, this\npackage provides functions accessing the data such as\nprob_random returning the posterior probability that a given\nstring was produced by a random process. In addition, two\ntraditional (but problematic) measures of complexity are also\nprovided: entropy and change complexity.",
