On (Pointed) Minimum Weight Pseudo-Triangulations
In this note we discuss some structural properties of
minimum weight (pointed) pseudo-triangulations.
Optimal triangulations for a set of points in the plane
have been, and still are, extensively studied within Com-
putational Geometry. There are many possible opti-
mality criteria, often based on edge weights or angles.
One of the most prominent criteria is the weight of a
triangulation, that is, the total Euclidean edge length.
Computing a minimum weight triangulation (MWT) for
a point set has been a challenging open problem for
many years  and various approximation algorithms
were proposed over time; see e.g.  for a short survey.
