There's a CRAN Task View on optimization. There might be something useful there.

    Good afternoon,
    I am a Biology researcher working on Functional Morphology and Behaviour 
    in mammals. Nowadays, I have a series of morphological data that I would 
    like to test against different models for which I would need to optimize 
    them -namely, "randomly manipulating" all models parameters in order to 
    find the model that fit best upon my data.
    I've been told that the function "optim" is THE function for me, but 
    I've been having problems to program it and set all constraints.
    Is there anything you could help me (guide me) with? I've asked already 
    several "experts" in the internet but noone gave me a real solution.
    Thanks a lot, have a nice day,
