Abstract

We study the upward point-set embeddability of digraphs on one-sided convex point sets with at most 1 bend per edge. We provide an algorithm to compute a 1-bend upward point-set embedding of outerplanar stst-digraphs on arbitrary one-sided convex point sets. We complement this result by proving that for every n18n \geq 18 there exists a 22-outerplanar stst-digraph GG with nn vertices and a one-sided convex point set SS so that GG does not admit a 1-bend upward point-set embedding on SS.
