More important, the eoRealVectorBounds, vectorized version (a vector<eoRealBounds *> has also become an eoPersistent object and now derives from an eoRealBaseVectorBounds class. A useful consequence (and actual motivatino) was to be able to have soem eoValueParam<eoRealVectorBounds> with all possibilities for input (see doc for Lesson4 in the tutorial for the syntax).

/*
|
|
* This function builds the operators that will be applied to the eoReal
|
|
*
|
|
* It uses a parser (to get user parameters) and a state (to store the memory)
|
|
* the last argument is an individual, needed for 2 reasons
|
|
* it disambiguates the call after instanciations
|
|
* some operator might need some private information about the indis
|
|
*
|
|
* This is why the template is the complete EOT even though only the fitness
|
|
* is actually templatized here: the following only applies to bitstrings
|
|
*
|
|
* Note : the last parameter is an eoInit: if some operator needs some info
|
|
* about the gneotypes, the init has it all (e.g. bounds, ...)
|
|
* Simply do
|
|
* EOT myEO;
|
|
* _init(myEO);
|
|
* and myEO is then an ACTUAL object
