Following a Moving Optimum with an ES

The animation below depicts a (15, 100)-ES following the moving optimum (indicated by a light blue star) of a (modified) 30-dimensional Fletcher-Powell function.

Due to memory limits and in order not to overcrowd the pictures with green diamonds each of the 70 frames only displays the best five individuals of 10 consecutive generations.

IDL produced the original animation.

The resulting GIF's were put together with a tool called gifmerge by Mark Podlipec.
