> I like to think of Robin Hood hash tables with linear probing as arrays sorted on uniformly distributed keys, with gaps. That makes it clearer that we can use these tables to implement algorithms based on merging sorted streams in bulk, as well as ones that rely on fast point lookups. A key question with randomised data structures is how badly we can expect them to perform.
