Random Generation of Directed Acyclic Graphs
Electronic Notes in Discrete Mathematics, 2001 Abstract Abstract We propose a simple algorithm based on a Markov chain for generating acyclic digraphs with a given number of vertices uniformly at random. In addition, standard combinatorial techniques allow us to describe the overall shape and average edge density of an acyclic digraph.

How to Layer a Directed Acyclic Graph
, 2002 We consider the problem of partitioning a directed acyclic graph into layers such that all edges point unidirectionally. We perform an experimental analysis of some of the existing layering algorithms and then propose a new algorithm that is more ...
