Detailed Description

template<class T, class ERRF, class DAT = dataframe>
class vita::sum_of_errors_evaluator< T, ERRF, DAT >

An evaluator to minimize the sum of some sort of error.

Template Parameters

T	type of individual
ERRF	the error functor. It returns a measurement of the error that a given program commits in the current training case (DAT::example)
DAT	type of the dataset

This class drive the evolution towards the minimum sum of some sort of error.
