KC_LZ.py contains the python implementation of the version of Lempel-Ziv (LZ) complexity defined and used in Dingle et al. Input–output maps are strongly biased towards simple outputs (Nature comm, 2018).
To use, in your own script: from KC_LZ import calc_KC, and then evaluate the complexity of a string x doing calc_KC(x). It is currently desinged for binary strings, but the code would trivially be extended to larger alphabets.
See also the sandbox for experiments in other variants of LZ complexity. In complexities.py, there are other complexity measures mostly for Boolean functions expressed as binary strings.
