Non-const operator() for CostFunctor?

[David Banas]

Is it possible to use a non-const operator() in a CostFunctor?

[Sameer Agarwal]

No, because we need to be sure that the cost function/functor is not changing between calls.

Okay, thanks.

Do you have any sample code that shows how to correctly "wire in" an objective function, which must be implemented outside of the CostFunctor struct definition?

I just can't figure out how to properly dance around that existentially typed operator(); sorry. :(

Thanks,

David,

Do you have a function that computes part of whole of the objective function which is a library function that you need it call from your cost function?

In that case this section of the documentation maybe of use
