Since Galapagos only cares about inputs (sliders) and outputs (a single number describing fitness), you should be able to rip out everything sensitive in between and replace it with something simple and shareable. Did you manage to use Galapagos on a simple case (like fitting a circle to some points, or some such trivial task)? If you haven’t tried that, I’d recommend starting there. Pick something where you can see that the answer is correct just to get a feel for the software.
Do note that there are setups where Galapagos will not be able to find an answer. The input sliders need to have a certain amount of continuity (sometimes called ‘linearity’). That means that a slight perturbation of a slider results in only a slight change in fitness. If there are too many sudden jumps in fitness, then GP will get lost too easily.
Of course in practice certain continuous setups are also unsolvable simply because a single iteration takes too long to compute. GP will need a couple hundred stabs before it starts generating suggestions that are even half-way worth considering.
