Flip distance and triangulations of a ball
WebOct 14, 2024 · Abstract: Given a set $\cal P$ of points in the Euclidean plane and two triangulations of $\cal P$, the flip distance between these two triangulations is the minimum number of flips required to transform one triangulation into the other. Parameterized Flip Distance problem is to decide if the flip distance between two given … WebWang, D., Wang, X., Li, S., & Zhang, S. (2008).

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 ...

WebIt is known that computing the flip distance between two triangulations of a simple polygon or of a point set is NP-hard. The latter is known to be fixed-parameter tractable [ 33 ]. On the other hand, the NP-hardness of computing the flip distance between two triangulations of a convex polygon is a well-known open question [ 12 , 13 , 17 , 34 ... WebFeb 10, 2024 · The flip distance between two triangulations of \(\mathcal{{P}}\) is the minimum number of flips needed to transform one triangulation into the other. The Flip Distance problem asks if the flip distance between two given triangulations of \(\mathcal{{P}}\) is at most k, for some given \(k \in \mathbb {N}\). It is a fundamental and …
