Hi,

AnyBody uses three different muscle models:

AnyMuscleModel
AnyMuscleModel3ELin
AnyMuscleModel3E

I think i have understood the difference between these three models and I'm
using mainly the AnyMuscleModel and the AnyMuscleModel3E, as the results are
mainly in a good range.

But I have a question regarding the optimization algorithm. Am I right with the
assumption that I can choose for each of theses models one of the following
algortihm in AnyBody?

- Polynomial criteria
- Soft saturation criteria
- The min/max criterion

As I know from the work of Forster, 2003, the results can be quite different
between linear or a quadratic solver solution.

Is my assumption right, that the min/max criterion is the simplex solver? If
then, what is the addition for example MinMaxNRsimplex for?

If I want to apply a quadratic algorithm I have to change the Penalty form LP to
QP, but what influence has then the simplex solver?

As I see mainly the MinMaxNRSimplex solver in the models of the repository, it
is advisable to use a quadratic solver? Is it beacuse the simplex solver is more
efficient and robust?

I hope you can make this more clear to me.

Best regards,

THomas
