Detailed Description

template<class T, bool S>
class vita::basic_reg_lambda_f< T, S >

Lambda function specialized for regression tasks.

Template Parameters

T	type of individual
S	stores the individual inside vs keep a reference only. Sometimes we need an autonomous lambda function that stores everything it needs inside (it will survive the death of the individual it's constructed on). Sometimes we prefer space efficiency (typically inside an evaluator)
