ROOT::Minuit2::NegativeG2LineSearch Class Reference

Description

In case that one of the components of the second derivative g2 calculated by the numerical Gradient calculator is negative, a 1dim line search in the direction of that component is done in order to find a better position where g2 is again positive.
