Now contains all code, scripts and data for Stivala (2023) "Geodesic cycle length distributions in fictional character networks" https://arxiv.org/abs/2303.11597
Includes Python implementation of algorithm to test if a cycle is geodesic directly according to definition, and also the Lokshtanov (2009) algorithm for finding the longest isometric cycle, with the correction of Catrina et al. (2021) to work correctly for odd-length cycles.
