good correlation with the ground truth is attained earlier whereas for smaller values of the noise it takes longer to find it so this is non-intuitive nevertheless this is what is happening here that's the property of the launch of algorithm in this problem and in the inside i'm just comparing to the very same lines for the approximate message passing algorithm which is another iterative but not gradient based algorithm that one that one behaves in the intuitive way the easier ones get there earlier but not for the longevity
