+			It should be noted that the normal distribution in \eqref{eq:transShortestPath} and \eqref{eq:transMultiPath} does not integrate to \SI{1}{} due to circularity of angular data. 
+This normally requires wrapped distributions like the von Mises distribution. 
+However, in our case, the normal distribution can be assumed as sufficient for small enough $\sigma^2$.
