Least squares is a kind of maximum likelihood optimization. There are plenty of routines for that, like MPFITFUN or CURVEFIT.

I guess you mean you have your own likelihood function which is not least squares. There is no real ready-made IDL routines for that. You have to rely on general routines like CONSTRAINED_MIN, AMOEBA, etc.
