Where is alpha in DART codes?

Hi, I have been running the codes of DART, which seems does not agree with the closed solution proposed in the paper. At least, I did not even see the alpha variable as shown in Algorithm 1. Looks forward to your response. Thanks!

Hi, thanks for your interest in the paper and code. Alpha is incorporated in the algorithm effectively as a prior to scale up/down the magnitude of noise. It was not used in these simulation experiments. Here, the noise parameter is computed as in Equation 3 in the paper.
