Tight Bounds for Classical Open Addressing
We introduce a classical open-addressed hash table, called rainbow hashing, that supports
a load factor of up to 1 -ε, while also supporting O(1) expected-time queries, and …

SPIDER: Improved Succinct Rank and Select Performance
Rank and select data structures seek to preprocess a bit vector to quickly answer two kinds
of queries: rank (i) gives the number of 1 bits in slots 0 through i, and select (j) gives the first …
