This page contains some additional data related to the article Recombining Angles in Differential Evolution.
The graphs in Figure 6 is based on the data from experiments on the Folding Rule Problem and the Restricted Folding Rule Problem.
The experiments on the Folding Rule Problems where performed on a simple implementation in Java. The implementation is available here.
The molecule minimization experiment was performed with a simple Python implementation which is available here. The zip file also includes the results from the experiments along with the input file used. The program requires Pybel and Open Babel version 2.2.0.
