One of the invalidator operators. Use this one as a 'hat' on an operator
|
|
that is defined to work on a generic datatype. This functor will then check
|
|
the return type of the operator and invalidate the fitness of the individual.
|
|
|
|
This functor is used in algorithms that work with straight eoMonOp, eoBinOp
|
|
or eoQuadOp operators, for instance eoSGA. Note that eoGenOp derived operators
|
|
generally do invalidate the fitness of the objects they have changed.
|
|
|
|
Return value means "Has_Changed" and not "Needs_To_Be_Invalidated"
|
|
as successive invalidation are not really a problem
