Try pls Mathcad Server with your test function f(x, y) - http://twtmas.mpei.ac.ru/mas/Worksheets/Minimum.mcd

PS I would like to create a video but sorry - no time.
I guess the question (implicitely) also was if you would be so kind and share the worksheet :-)

Just one more question, xb, xe and yb, ye is the range (in this case for two variables) where the function looks for the minimum ?
