Auto-guess non-linear fit coefficients

How does Igor auto-guess coefficients for curve fitting? What is the algorithm used?
I guess Wavemetrics payed some employees quite a bit of money to code this by hand and to carefully tweak the algorithm :-)

Maybe if you post your formula, somebody has an idea how to do sufficient initial guesses...

Exactly.
