Actually, with FindMinimum it's a little more complicated than what I
said because I think it has some kind of heuristic to realize when the
first argument isn't a numeric function in held form - then
FindMinimum evaluates the argument to make the optimization work. I
guess that is for compatibility with old code. However, the heuristic
doesn't work if there is an option present.
FindMinimum::"fdssnv" : Search specification guesses without variables
should be a list with a 1-4 elements.
Maybe I should just have started with Plot, but I hope I got the
original question across.
