Data Structures and Algorithms 2020-10-20 v3

Abstract

Given a graph G=(V,E)G=(V,E), the longest induced path problem asks for a maximum cardinality node subset WVW\subseteq V such that the graph induced by WW is a path. It is a long established problem with applications, e.g., in network analysis. We propose novel integer linear programming (ILP) formulations for the problem and discuss efficient implementations thereof. Comparing them with known formulations from literature, we prove that they are beneficial in theory, yielding stronger relaxations. Moreover, our experiments show their practical superiority.
