我们提出了一种加速的无梯度方法,该方法具有与p-范数(1≤p≤2)相关的非欧几里得近端算子。在计算函数值的低噪声条件下,得到了该方法的收敛速度估计。我们给出了计算实验的结果。
We propose an accelerated gradient-free method with a non-Euclidean proximal operator associated with thep-norm (1 ⩽p⩽ 2). We obtain estimates for the rate of convergence of the method under low noise arising in the calculation of the function value. We present the results of computational experiments.
