Successive operations during step 3. Upper row: output of steps 1 and 2. Bottom row; from left to right: construction of the initial graph (3-a), extraction of min-weight spanning forest (3-b), and root crossing resolution (3-c). The vertex colormap indicates their label, from 4 (red) to 13 (yellow), and the colormap of edges indicates their weight, from 0 (bright yellow) to 2 (red). White arrows: in the case of root crossing, the corresponding pathways in the graph are disconnected during step 3-b and reconnected in step 3-c
