Abstract

This paper presents a ZBDD (Zero-Suppressed Binary Decision Diagram) based framework that solves a collection of graph optimization problems. We show how these problems reduce to three primitive problems, and how the later can be solved exactly using ZBDDs. The application of this framework is illustrated on multilayer planar routing, where it can solve real-life instances that cannot be handled otherwise.
