Minimal Set of Constraints for 2D Constrained Delaunay Reconstruction

Abstract : Given a triangulation $T$ of $n$ points in the plane, we are interested in the minimal set of edges in $T$ such that $T$ can be reconstructed from this set (and the vertices of $T$) using constrained Delaunay triangulati- on. We show that this minimal set consists of the non locally Delaunay edges of $T$, and that its cardinality is less than or equal to $n+i/2$ (if $i$ is the number of interior points in $T$), which is a tight bound.
