Brief Announcement: Partial Reversal Acyclicity

摘要

Partial Reversal (PR) is a link reversal algorithm which ensures that an initially directed acyclic graph (DAG) is eventually a destination-oriented DAG. While proofs exist to establish the acyclicity property of PR, they rely on assigning labels to either the nodes or the edges in the graph. In this work we show that such labeling is not necessary and outline a simpler direct proof of the acyclicity property.
