....and it is required to store D in such a way that on query string q, the member of D closest to q in Hamming distance be retrieved. The version where all members in D of distance d or less from q be retrieved is the Approximate Query (AQ) problem of [6] Most of the work on these problems (see [9] and the references therein) focuses on deterministic schemes. However, deterministic hashing schemes are rather limited, especially for the dynamic dictionary problem (e.g. 2] so we resort to randomized tools. We were much inspired by the landmark paper by Fredman Koml os and Szemer edi [5] ....

Linial and Sasson [20] devise a noisy hashing scheme for a one dimensional universe U and a one dimensional memory M , with any noise measure Delta. It is a nonexpansive hashing scheme, i.e. one which translates every ....

....the hashing function. Moreover, elements y 2 D x might be hashed to distant locations in the memory. Large memory is usually paged, in which case the procedure might require access to W(jD x j) different pages. The problem of hashing noisy data appears in several variants in many applications (see [13, 8, 6, 15] and references therein) Linial and Sasson [12] devise a noisy hashing scheme for a one dimensional universe U and a one dimensional memory M , with any noise measure D. It is a non expansive hashing scheme, i.e. one which translates every D neighborhood in U to a constant number of ....
