Me again! Smile

I changed the behavior of my FU, creating a gradient for values of x<(-5)
It returns 10*(-x).
Starting from (-30,0) with length of .5, 1 or 2 the simplex stays in the wrong valley (-3.778,0).
With length of 50 (zum beispiel), the right valley is found (1.227,0).
Your algorithm is really well built.

Regards.
