Hi Pratim,

if you can spezify a ringe in which the variables for the minimum lie,

you can spezify this in the first Slot of NMInimize.E.g. assume that

form f[x,y]= (x - 3)^2 + (y - 5)^2 it is know that xmin is in 2..4 and

ymin in 4..6:

NMinimize[{(x - 3)^2 + (y - 5)^2, 2 < x < 4, 4 < y < 6}, {x, y}]
