WebMap topology. Topological editing is an editing mode that constrains coincident geometry to an ordered graph of topologically connected edges and nodes. It requires no setup and operates only on visible features … WebDec 23, 2014 · Topological sorting is not required if you greedily process nodes everytime an update happens. If you greedily revisit all neighbours which you can improve the longest distance. For example at 9, you can just check that 9+1 > 7 and revisit the 7th node to update it. BUT just to clarify, the big O gets worse.
