Computational Design # (Galapagos)

Hi All!

I am trying to create a display Parameter diagram for my Galapagos iterations but it does not seem to work properly, Does anyone know why this is happening (image)?

I was also wondering what the galapagos fitness value represents exactly. In my case, the fitness was intended to minimize the total radiation of the tower floors. However, the results from galapagos are decimal values. Is there a way to know how much radiation these values represent?

Are greater fitness values better than smaller ones?

The original script that I created to display the parameter variation diagram was based on three sliders that each had bounds of 0 to 10. As you can see from the screenshot below, the bounds of your sliders vary greatly and that is what is causing your display issue.

To solve this issue you will need to remap the numbers output to be consistent. Since you are doing this, it might help to add numeric values for each extreme and labels to your diagram. There is a way to write this script so that it automatically includes the normalization and labels, but I wanted to make sure the students still had some work to do!

The Ladybug radiation analysis component you are using outputs total radiation (your fitness value) in kWh and it appears that you doing the analysis over the course of a single day in June. From this information I would assume that you have very little radiation falling on your floor plates since it is a decimal value. Perhaps you should consider using a larger time period (one month or more) if you want bigger values. But regardless, the time period should be selected in such a way that it can help you make a design decision about your building. So what is the story that you are telling and over what time period will radiation values help you tell this story?
