What's to stop the discovered solutions from being similar? Nothing but the dimensions of interest. If the best solutions with respect to features a, b, and (a&b) are all the same, then it does not seek different solutions.
This may indicate you chose reduntant features though.
Here's an interesting application that provides some motivation.

- sevensor 9y agoRegarding the similarity of solutions: If, in a particular region, your model outputs are particularly sensitive to the inputs, that region can be overrepresented in a feature map. What I mean by this is that we cannot effectively choose between the solutions in this region -- the region is small compared to our ability to control inputs. Overrepresenting such a region in a population-based search starves the rest of the problem space of the algorithm's attention. Thanks for the link, by the way -- this is a particularly interesting application.
