Resumo


A Gallai vertex in a graph is a vertex that belongs to all of its longest paths. In this paper, we study the implementation of a parallel algorithm to check if a given graph has a Gallai vertex. We implemented this algorithm purely with genAI and evaluated how well it could parallelize the algorithm using OpenMP. We confirmed a preexisting conjecture about the smallest cubic graph with no Gallai vertex and observed that genAI could implement and parallelize the algorithm in different granularities.
