Here is Nelder-Mead (both plain a and grid-restrained, use the latter) 
for CL:

BTW, maximum likelihood violates the likelihood principle.  I you want to 
do your statistics right, use Bayesian analysis.  CL is especially good 
for the latter, since you can write very fast iterations for MCMC.

HTH,

Hi, thanks. Yes you're right, ML is not the best, and indeed I had
used something bayesian before (MCMC) and then something in between
the two schools that I am currently using now: I have coded the
"simulated annealing" algorithm into lisp, which was honestly pretty
neat. But it goes a little slow (slowness not related to lisp or any
programming language, it's just the nature of the algorithm that it's
slow) and that's why I ask about nelder-mead because I wanted some
quick and dirty alternative.
