Nonlinear Fit algorithms

in a previous version of Mathematica, a simplex downhill method could be
opted for before switching on Levenberg+... . I regret that the old
simplex method is no longer available because I have trouble finding
global minima in many dimensions. 

(1) Is it pointless to use the Nelder Mead method? 

(2) If not, where do I find this code that was previously available? 

(3) Or what is your alternate suggestion? 

Thank you in advance for your comments, yours
