(a) A couple of correct edges with no node in their Gaussian neighborhood. (b) The effect of close nodes to a shortcutting edge’s utility function as the inner product of the node’s and edge’s Gaussian convolution. The standard deviation of the Gaussian kernel is selected such that farther nodes have negligible effect on the shortcutting degree.
