Modification Problems Toward Proper (Helly) Circular-Arc Graphs

pdf-format:
LIPIcs-MFCS-2023-31.pdf (0.7 MB)

Abstract

We present a 9^k ⋅ n^O(1)-time algorithm for the proper circular-arc vertex deletion problem, resolving an open problem of van ’t Hof and Villanger [Algorithmica 2013] and Crespelle et al. [Computer Science Review 2023]. Our structural study also implies parameterized algorithms for modification problems toward proper Helly circular-arc graphs.
