That is, f grows at least at the same asymptotic rate as g. Equivalently, f is asymptotically bounded from below by g. See Figure 1-4. 4. f (n) = o(g(n)), to be read as “f of n is little oh of g of n,” if and only if for every positive constant C there is a positive integer n0 such that f (n) < Cg(n) whenever n ≥ n0.
