Choosing an optimal learning rate for LMS algorithm is difficult due to it's sensitivity to input data scaling. Normalised LMS resolves this issue by normalising with the power of input.
The learning rate value of the NLMS algorithm is constant across all iterations. Without outside interference present, the optimal learning rate on NLMS is 1. When outside interference is present, optimal learning rate for NLMS is given by

(Note the minus sign at the bottom entry of the summing junction on the left.) Block H and G represent LTI systems; H has transfer function HL and G has transfer function GL. All blocks are causal (so that the closed-loop system is causal as well). Both z and d are...
