WebJan 12, 2024 · The Parameterized Flip Distance problem is to decide if the flip distance between two given triangulations is equal to a given integer k. The previous best FPT algorithm runs in time O^*(k\cdot c^k) (c\leq 2\times 14^11), where each step has fourteen possible choices, and the length of the action sequence is bounded by 11k. WebJul 10, 2014 · Theorem 3 is the most important result of the section because it relates the flip distance of two triangulations with that of two triangulations with fewer vertices. A more general result on flip-graphs can be obtained from the main arguments in the proof of this theorem: consider some vertex a of a convex polygon π.If U and V are two …
WebThe flip distance between two triangulations is the minimum number of flips needed to transform one triangulation into another. It can also be described as the shortest path … Webip distance between any two triangulations of a convex polygon is at most 2n 10, for n>12, as shown by Sleator, Tarjan, and Thurston [15] in their work on the ip distance in convex polygons. The latter case is particularly interesting due to the correspondence between ips in triangulations of convex polygons and rotations in binary trees: The ...
