We now present the efficiency gains that HiMap achieves at constant 𝑛 and 𝑘 compared to radial designs and LOMAP 2.0. Since both LOMAP and radial designs have inflexible edge counts, we set 𝑘 for the optimal designs to that of the reference design. For reference, LOMAP designs contained 1.2 -1.5 edges compared to the 𝑛 -1 edge count of radial designs (Table ).
