The nodes in Tare denoted by small letters (possibly with a subscript) such as u, ur, etc., the edgeq are denoted by node pairs such as @,q)# an8 the distance (positive numbers) associated with the ‘edp !‘u, ui) is denoted by dt% q)w The path k#gfh lhO) is defined as the sum of edge lengths in the uniquely defined path between u and v. The total path kgth of’ T wtph wpect to u, L(u), is defined as
