Galapagos works strictly with integer variables. If your slider goes from 0.0 to 2.0 with three decimal places, there’s a total of 2001 unique values it can assume. Galapagos treats this slider as an integer value between 0 and 2001.
Any changes made to the slider accuracy or domain may result in a different number of discrete states and that would seriously complicate the algorithm.
Also it would mean that state 258 would map to a different numerical value than it used to, so now the model and Galapagos’ understanding of the model are diverging.
