The Power of Team Exploration: Two Robots Can Learn Unlabeled Directed Graphs
We show that two cooperating robots can learn exactly any strongly-connected directed graph with n indistinguishable nodes in expected time polynomial in n. We introduce a new typ...

Multiple-Source Shortest Paths in Embedded Graphs
Let G be a directed graph with n vertices and non-negative weights in its directed edges, embedded on a surface of genus g, and let f be an arbitrary face of G. We describe an alg...

On-Line Construction of Symmetric Compact Directed Acyclic Word Graphs
The Compact Directed Acyclic Word Graph (CDAWG) is a space efficient data structure that supports indices of a string. The Symmetric Directed Acyclic Word Graph (SCDAWG) for a st...

Clustering by weighted cuts in directed graphs
In this paper we formulate spectral clustering in directed graphs as an optimization problem, the objective being a weighted cut in the directed graph. This objective extends seve...

Hierarchical Layouts of Directed Graphs in Three Dimensions
Abstract. We introduce a new graph drawing convention for 3D hierarchical drawings of directed graphs. The vertex set is partitioned into layers of vertices drawn in parallel plane...
