\subsection{Detailed Description}
|
|
Prints snapshots of fitnesses to a (new) file every N generations.
|
|
|
|
Assumes that the parameters that are passed to the monitor (method add in {\bf eo\-Monitor.h}{\rm (p.\,\pageref{eo_monitor_8h})}) are {\bf eo\-Value\-Param}{\rm (p.\,\pageref{classeo_value_param})}$<$std::vector$<$double$>$ $>$ of same size.
|
|
|
|
A dir is created and one file per snapshot is created there - so you can later generate a movie!
|
|
|
|
TODO: The counter is handled internally, but this should be changed so that you can pass e.g. an evalcounter (minor)
|
|
|
|
I failed to templatize everything so that it can handle {\bf eo\-Param}{\rm (p.\,\pageref{classeo_param})}$<$std::vector$<$T$>$ $>$ for any type T, simply calling their get\-Value method ...
