WebMay 27, 2015 · You can definitely do a cuckoo hashtable with a single hash table; that is, where the two positions for each object are simply positions within a single hash table. The only small problem to be solved is how to decide during the cuckoo eviction loop which of the two positions to use for an evicted key. WebCuckoo Hashing Cuckoo hashing is a simple hash table where Lookups are worst-case O(1). Deletions are worst-case O(1). Insertions are amortized, expected O(1). Insertions …
