[Quantlib-dev] unreferenced formal parameter in Line-search based optimization method

[Ferdinando A. <na...@am...>]

Hi all

the implementations in derived classes (ConjugateGradient, BFGS,
SteepestDescent) of

LineSearchBasedMethod::getUpdatedDirection(Problem &P,
                                           Real fold,
                                            Real gold2,
                                           const Array& gradient) = 0;

never use the second parameter Real fold.

Is the parameter to be removed or it might be used by some future
line-search based optimization method?

Nicolas, Frédéric? Anyone else?

ciao -- Nando
