WebbRandomized algorithms are often enjoyed for their simplicity, but the hash functions used to yield the desired theoretical guarantees are often neither simple nor practical. Here we show that the simplest possible tabulation hashing provides unexpectedly strong guarantees. The scheme itself dates back to Carter and Wegman (STOC'77). WebbZobrist Hashing is an instance of tabulation hashing [6], a method for constructing universal families of hash functions by combining table lookup with exclusive or operations. Zobrist Hashing was rediscovered by J. Lawrence Carter and Mark N. Wegman in 1977 [7] and studied in more detail by Mihai Pătrașcu and Mikkel Thorup in 2011 [8] [9] .
Webb2.4 Simple Tabulation Hashing [3] The last hash function presented is simple tabulation hasing. If we view a key xas a vector x. 1;x. 2;:::;x. c. of characters, we can create a totally random hash table T. i. on each character. This takes O(cu. 1=c) words of space to store and takes O(c) time to compute. In addition, simple tabulation hashing ... Webb(algorithm) Definition: The hash value is the xor of values from tables indexed by characters. Formal Definition: h(c) = ⊕ n i=1 T i [c i], where ⊕ is the xor operation, T i is the i th table, and c i is the i th character. Generalization (I am a kind of ...) hash function. Aggregate parent (I am a part of or used in ...) twisted tabulation hashing.. See also …

While this scheme is not even 4-independent, it is shown that it provides many of the guarantees that are normally obtained via higher independence, e.g., Chernoff-type concentration, min-wise hashing for estimating set intersection, and cuckoo hashing.
