“…After several rounds of revisions and reviewing, six of the submitted articles were accepted for inclusion in the Special Issue. These six articles present new results for a wide variety of data structures with unexpectedly diverse applications: the link-cut tree (Russo et al [1]), the distributed combinatorial map (Damiand et al [2]), the sliding suffix tree (Brodnik and Jekovec [3]), the DenseZDD (Denzumi et al [4]), the dynamic DFS tree (Nakamura and Sadakane [5]), and the selectable sloppy heap (Dumitrescu [6]). As a whole, they represent some of the current trends in the field.…”
