Abstract

In this paper, as a pattern matching for rooted labeled caterpillars (caterpillars, for short), we discuss a subcaterpillar isomorphism between caterpillars whether or not a pattern caterpillar is a subcaterpillar of a text caterpillar. Then, we design the algorithms to solve it by simplifying the algorithms for subcaterpillar isomorphism (between a caterpillar and a tree) when a pattern caterpillar is a subcaterpillar of a text tree designed by Miyazaki and Hirata (2022). These algorithms run in O(hHσ) time and O(h) space, where h is the height of a pattern caterpillar, H is the height of a text caterpillar and σ is the number of labels in the caterpillars. Finally, we give experimental results of computing these algorithms by comparing with subcaterpillar isomorphism and caterpillar inclusion.
