## Root Mean Square Error Interpretation

This seems to have more sense if we consider the noise in the system as pure additive Gaussian noise (i.e. $y = f + ae$, where $a$ is the standard deviation http://www.gepsoft.com/gxpt4kb/Chapter10/Section1/SS06.htm Thus, in this case, raw maximum fitness rfmax = 1000. Root Mean Square Error Formula So we are left with maximizing $$-\frac{(y_{obs} - y_{pred})^2}{(ay_{obs} + b)^2}$$ Which is the same is minimizing the the value at the beginning of the answer.
