Bei der Hartman Funktion ist als globales minimum der Wert -3.3224 hinterlegt. Geb ich die in der Funktion beschrieben Koordinaten ein, kommt aber der Wert -3.656287 heraus.

Erstellung der HartmannFunction
r = makeHartmannFunction(4)
r(c(0.20169,0.150011,0.476874,0.275332))

Diese Angaben sind für die Hartmann Function hinterlegt:
"Name: 4-d Hartmann Function
