Short answer: the evaluations per iteration depend on the solver used and the dimension.

> Hi all,
> I am performing FORM analysis and I am setting the maximum number of iterations
> to 100. In many occasions I see that the performed number of evaluations is
> larger than 100.
> My questions are two:
> 1- what does the number of evaluation represents and in what it differs from the
> iterations?
> 2- I can set the max number of iterations as a convergence criterion but is
> there a way to control the evaluations?

> Thank you for your time!
