One of the earliest results in this area is the upper bound on flip distance proved by Culik et al. [4]. Precisely, the flip distance between two polygons (P,P′) ∈P nis at most 2n−6 for all (P,P′) ∈P n. Later, Sleator et al. [12] improved ...

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 ...
