Abstract
We present an O(¦ E ¦2¦ V ¦ log ¦ V ¦) algorithm for the construction of the principal partition of a graph. The best known earlier algorithm for this problem is O(¦ E ¦3 log ¦ V ¦). Our approach differs from the earlier approaches in that it is node-partition based rather than edge-set based. We use flow maximisation as our basic subroutine.
