Hello everybody,

I have another question.

I have seen there is a function called "constrOptim" in R.

Is it better than "optim", for example to optimize a function f of two parameters belonging to [0,1] and [0,Infinity] ? Do the methods supplied like Nelder-Mead are better than those of optim ?

Thank you very much.
