In this note, we report a practical algorithm to compute Goldstein ( , δ)-stationary points for L-Lipschitz function in finite time without subgradient selection procedure in every oracle calls. The new algorithm removes the impractical first-order oracle assumption in Zhang et al. [2020] with a random conic perturbation.
