Detailed Description

Cost function for the Cumulative Gaussian Optimizer.

The Cumulative Gaussian is defined as the integral of a normalized Gaussian over the domain \( [-\infty, \infty] \).

Let G(x) be the normalized Gaussian defined as
\( G(x) = \frac{1}{{\sigma \sqrt {2\pi } }}e^{ - \frac{{\left( {x - \mu } \right)^2 }}{{2\sigma ^2 }}} \). The Cumulative Gaussian, is acquired by integrating G(x) then scaling and offsetting it by the lower asymptotes \( I_1 \) and upper \( I_2 \): \( C\left( x \right) = I_1 + \frac{{I_2 - I_1 }}{2}\left( {1 + erf\left( {\frac{{x - \mu }}{{\sigma \sqrt 2 }}} \right)} \right) \), where \( C\left( { - \infty } \right) = I_1 \) and \( C\left( \infty \right) = I_2 \).
C(x) can only be tabulated since it's a variation of the
error function. It is included in this class as the function EvaluateCumulativeGaussian, where the argument of the function is \( {\frac{{x - \mu }}{{\sigma \sqrt 2 }}} \).
