Summary: We give linear and polynomial time algorithms for computing a minimum hull-set in distance-hereditary and chordal graphs respectively. Prior to our result a polynomial time algorithm was only known for sub-classes of considered graph classes. Our techniques allow us to give at the same time a linear time algorithm for computing a minimum geodetic set in distance-hereditary graphs.
