Release 4.4.3 Addressing issue 231, failures in corner cases with large population size, by increasing the step-size damping of CSA and TPA. This seems also to improve the performance on bbob-f24 in 10 and 20-D while worsening the performance on bbob-f23 in 10 and 40-D. Provide option 'TPA_dampfac' analogous to 'CSA_dampfac'. Plots now show the current best solution and the distribution mean in two subplots. New: Provide the two (by far) most useful statistical tests with a tidy interface in cma.utilities.math.test... Provide a more_algorithms sub-package containing purecma and CompactGA. Provide a provisional experimentation module (requires import cma.experimentation). A few smaller fixes and improvements.
