Abstract

The cutwidth is an important graph-invariant in circuit layout designs. The cutwidth of agraph G is the minimum value of the maximum number of overlap edges whenG is embedded into a line. A caterpillar is a tree which yields a pathwhen all its leaves are removed. An iterated caterpillar is a tree which yields acaterpillar when all its leaves are removed. In this paper we present an exact formula forthe cutwidth of the iterated caterpillars.
