Dynamic Fractional Cascading` ••
... fractional cascading also supports insertions into and deletions from the lists efficiently. More specifically, we show that a search for a key in n lists takes time O(1og N +n log log N) and an insertion or deletion takes time O(log log N). Here N is the total size of all lists. If only insertions ...
