\subsection{Detailed Description}
|
|
Defines bound classes for real numbers.
|
|
|
|
Scalar type: ------------ Basic class is eo\-Real\-Bounds, a pure virtual.
|
|
|
|
The following pure virtual methods are to be used in mutations:\begin{itemize}
|
|
\item void folds\-In\-Bounds(double \&) that folds any value that falls out of the bounds back into the bounds, by bouncing on the limit (if any)\item bool is\-In\-Bounds(double) that simply says whether or not the argument is in the bounds\item void truncate(double \&) that set the argument to the bound value it it exceeds it\end{itemize}
|
|
|
|
|
|
So mutation can choose\begin{itemize}
|
|
\item iterate trying until they fall in bounds,\item only try once and \char`\"{}restd::pair\char`\"{} by using the folds\-In\-Bounds method\item only try once and restd::pair using the truncate method (will create a huge bias toward the bound if the soluiton is not far from the bounds)\end{itemize}
|
|
|
|
|
|
There is also a {\bf uniform()}{\rm (p.\,\pageref{classeo_real_bounds_a11})} method that generates a uniform value (if possible, i.e. if bounded) in the interval.
|
|
|
|
Derived class are {\bf eo\-Real\-Interval}{\rm (p.\,\pageref{classeo_real_interval})} that holds a minimum and maximum value, {\bf eo\-Real\-No\-Bounds}{\rm (p.\,\pageref{classeo_real_no_bounds})} the \char`\"{}unbounded bounds\char`\"{} (-infinity, +infinity) {\bf eo\-Real\-Below\-Bound}{\rm (p.\,\pageref{classeo_real_below_bound})} the half-bounded interval [min, +infinity) {\bf eo\-Real\-Above\-Bound}{\rm (p.\,\pageref{classeo_real_above_bound})} the half-bounded interval (-infinity, max]
