Hello to everyone,
I’ve already searched on the forum something about this, but I did not find nothing. I did an optimization s facade with galapagos, but at the end of it, when i check the record, all the fitness voices are:“Fitness:Nan”. And there aren’ t any kind of graphs in the solver s window.
Please, someone could helps me? if you would like to check the script I will attach
Best,
Luca
NaN means Not-a-Number, meaning all your computed fitness values are unset. Perhaps you’re dividing by zero or doing some other illegal mathematical operation?
I can’t run your file because it requires all manner of additional installed software which I don’t have, but either you’re feeding invalid numbers or null values into the Galapagos fitness node.
