For L-shade, different versions are included where more parameters are tracked, and used to generate the figures in the paper. - Modular_DE_code: The python code used for SHADE and L-SHADE. -DE_TIOBR: The notebooks used for generating data, processing it and creating the visualizations, More detail is included in the readme. -TIOBR_MathematicaNotebooks: Mathematica notebooks which were used to create figures 4, 12, 13 and 14 from the paper - Other rars: The files from SOS of running different DE versions on f0
