Multi-dimensional fitness evaluation #20

Open anandtrex opened 7 years ago

anandtrex commented 7 years ago

Should it be a weighted sum (as it is currently) or a lexicographic ordering?

maharjun commented 7 years ago

The major issue with lexicographical ordering is of floating point inequalities. The probability that the first elements of two fitness tuples are exactly equal is negligibly small. Thus what's gonna end up happening is that the further dimensions are never really going to come into consideration.
