Ok. I understand what you are saying. I guess I got my answer here. :) Thank you all.

I agree but is this (math.stackexchange.com/questions/9105/…) not going to happen here. I will get a polynomial equation for $\lambda$, which will be not solvable if degree is greater than 5.

I stated this question in a slightly different way here math.stackexchange.com/questions/9277/minimum-for-this-function

comment Minimum for this function
The larger problem I am trying to solve is math.stackexchange.com/questions/8046/… . I am fine with assuming the bounds on xi, since the minimum is going to be constrained by the bounds instead of going to $-infty$. The tricky part though is getting the minimum while making sure that $\sum x_i = 1$, otherwise I can take all $x_i$ to be 0.02 and that will result in minimum value for this function. I hope I am not just talking nonsense. Please correct me, if I am. Thanks.

Actually $\lambda$ is just a weight constant. Will the above bounds make any difference?

Right. its a concave function and so the minima is $-\infty$. I am thinking about adding some bounds and constraints. Something like $x_i \epsilon (0.02,1]$ and $\sum x_i = 1$.
