Description
I have experienced BestQuality values which exceeded 1 in SymbolicRegressionProbelms. Due to Gabriel Kronberger this should not be possible.
Steps to reproduce:
- New Genetic Algorighm
- New Symbolic Regression Problem (single objective)
- Run (it does not always happen, but if repeated a few times it occurs)
Attatches is a hl-file which shows in the Runs that the maximum quality was greater than 1 in a few runs.
