Fitness Normalization

[celsofranssa]

Hello,

My fitness implementation, looks like:

fitness = surprise + efficiency

Efficiency is a value in an interval between 0 and 1.
However, the surprise value can assume any value great than zero (actually very big values can occur).
These two elements must to have the same weigh in equation and, to reach that, I have to normalize the surprise for current entire population before sum with efficiency value.

Do you have any idea to make this in the framework?

Thank you so much!
Live Long And Prosper
