Thomas Neidhart commented on MATH-970:
--------------------------------------
The disadvantage of this approach is that the user has no means to know if the
solution is optimal (within the given epsilon bounds), or the optimizer has
just returned the last valid solution before exceeding the max iteration count.
I would prefer a SolutionCallback which contains the last valid solution. For
some optimizers this is very straight-forward, e.g. for the SimplexSolver you
just need a reference to the SimplexTableau and can derive from it the
solution. For other optimizers this may not be so simple.
> Provide a way to retrieve the best solution found so far when reaching the
> maxIteration limit in SimplexSolver
