WebNov 7, 2014 · That is, every directed edge has the form (v_i, v_j) with i < j. Each node except v_n has at least one edge leaving it. That is, for every node v_i, there is at least one edge of the form (v_i, v_j). Give an efficient algorithm that takes an ordered graph G and returns the length of the longest path that begins at v_1 and ends at v_n. WebOct 1, 2024 · With straight edges, overlaps with other plot elements are often inevitable. However, if we are allowed to plot curved edges, we can route each edge such that it avoids other nodes and edges as much as possible. This effect can be achieved by inserting control points into each edge, effectively segmenting each edge into short sub …
