[R] Optimization problem

[nntx]

As a simple example, I want to find minimum value for x^2, but it can't be
obtained by:
f<-function(x)x^2
optimize(f,lower=-1,upper=1)

What are other methods to deal with this? I tried DEoptim, still doesn't
work. Any suggustions will be extremely helpful! THanks!
