WebAny bitonic path ending at p2 has p2 as its rightmost point, so it consists only of p1 and p2. Its length is therefore p1p2 . Consider a shortest bitonic path Pij. If pj−1 is on its rightgoing subpath, then it immediately preceeds pj. The subpath from p1 to pj−1 must be a shortest subpath Pi,j−1, since we otherwise could replace it Web– Consider a shortest path from s to v, and let u be the vertex preceding v on path – u occurs before v in topological order, so d(s, u) = δ(s, u) by induction – When processing … WebWe are given one additional piece of information: for each vertex $v \in V$, the weights of the edges along any shortest path from $s$ to $v$ form a bitonic sequence.

WebNov 18, 2024 · A bitonic tour starts at the leftmost point and ends at the rightmost point. It consists of two paths, the upper and lower (imaging a line connecting the starting and end points), such that each point is visited by at least one of the paths. We describe a dynamic programming algorithm which uses partially constructed bitonic tours. WebKshitij Mishra posted a video on LinkedIn
