If anyone knows the correct terminology, I’ll update the thread title. I’m thinking about “Attribute Point” sliders in old video games I remember where you would have x amount of points to spread amongst your different stats, and as you raised one slider above the remaining point count, the other sliders would lower until you reach the maximum.
I think this would be handy in gene pool, but I imagine there must be something like it in an existing plugin or old forum post. I just don’t know what to search for.
Maybe you can try a negative weight to combinations whose sum exceeds the maximum.
This example (bottom screenshot of link) is linear. Perhaps you can use exponents.
