Design and Implementation of Efficient Data Types for Static Graphs

The LEDA library contains a very general and powerful graph type. This type provides the operations for all graphs of the library in one single interface. In many situations, however, this general interface is not needed and more specialized implementations of graphs could be used to improve the efficiency of graph algorithms. In this paper we present a design and an implementation of a family of special and efficient static graph types which fit into the LEDA environment of graphs and algorithms. They allow to speed up existing programs written with LEDA's standard graph type without changing the existing code.
