On the Approximation Hardness of Geodetic Set and Its Variantse this problem. Then, we show that there is no . polynomial-time approximation algorithm for edge geodetic number and strong geodetic number on subcubic bipartite graphs with arbitrarily high girth. We also prove that geodetic number and edge geodetic number are both LOG-.-hard, even on subcubic bip

Our lower bound matches the upper bound of Braverman–Rao–Raz–Yehudayoff (FOCS 2010, SICOMP 2014) for regular branching programs of alphabet size . except for a gap between their . term and our

,Optimization—Basic Ideas and Formulation,ace bound of Thorup and Zwick..It is not known, however, whether graph sparsity can help to get a stretch which is better than . using only . space. In this paper we answer this open question and prove a separation between sparse and dense graphs by showing that using sparsity it is possible to obta
