.... which attains the rate O P (n (p 1) 2p) More generally, Chen [3] and Polyak and Tsybakov [14] showed that for the class of p times di#erentiable regression functions (p 2) the optimal rate in a minimax sense is O(n (p 1) 2p) To deal with high dimensional problems Kushner and Clark [11], Polyak and Tsybakov [14] Spall [17] and others suggested randomized gradient estimators which need only two observations per step. The iterates of these methods converge still with the rate n 1 3 , but with the expense of a possibly higher asymptotic squared error. We show that these ....
....adopted in Theorem 3. Both Theorems show how to obtain estimators with unbiased limit distribution. In Section 5 it is shown how to obtain methods discussed in the previous literature as special cases of the kernel function approach. This includes the random direction method of Kushner and Clark [11] and the simultaneous perturbation method of Spall [18] Subsection 5.1) These methods can be generalized in a natural way to higher order methods (Subsection 5.2) A special kernel method proposed by Polyak and Tsybakov [14] fits in this framework as well. In the case of random vectors # n ....

....that the value of f i ( # w) depends on the output of the scheduler decision so that the updating algorithm should be dynamically adjusted according to scheduling decisions. Stochastic approximation is an effective technique for find ing zeros of a function f( which cannot be explicitly known [12]. If a noisy measurement is available, i.e. y = f(x ) e , where e denotes the observed noise, stochastic approximation recursively estimates the root for f( by x k 1 = x , 19) is the step size. If e is white noise and a converges to zero, x will converge with ....
....of no more than P # . With a scale factor of i=1 Y i on #,this equation can be further transformed into P # (25) Different stochastic algorithms require different conditions. General requirements include stationarity and a certain order differential. Readers are referred to [12] for a detailed discussion. We employ the same control parameter w i (k) as in MFS D and formulate the objective function of the scheduling block as w i (k)X i (k) 26) Together with the resource and rate constraints, this again is a Knapsack problem such that MFS P s scheduling block ....
