Compressed Index for Dictionary Matching [PDF]
The past few years have witnessed several exciting results on compressed representation of a string T that supports efficient pattern matching, and the space complexity has been reduced to |T| Hk (T) + o (|T| log sigma) bits, where Hk(T) denotes the kth-order empirical entropy of T, and sigma is the size of the alphabet.

Universal compressed text indexing [PDF]
The rise of repetitive datasets has lately generated a lot of interest in compressed self-indexes based on dictionary compression, a rich and heterogeneous family that exploits text repetitions in different ways. For each such compression scheme, several different indexing solutions have been proposed in the last two decades.

Practical Compressed Suffix Trees
The suffix tree is an extremely important data structure in bioinformatics. Classical implementations require much space, which renders them useless to handle large sequence collections. Recent research has obtained various compressed representations for

The wiener index of the zero-divisor graph for a new class of residue class rings
The zero-divisor graph of a commutative ring R, denoted by Γ(R), is a graph whose two distinct vertices x and y are joined by an edge if and only if xy = 0 or yx = 0.

Compressing relations and indexes [PDF]
We propose a new compression algorithm that is tailored to database applications. It can be applied to a collection of records, and is especially effective for records with many low to medium cardinality fields and numeric fields. In addition, this new technique supports very fast decompression.

Range Query Method Based on Compressed HMAC Algorithm for Sensor Networks [PDF]
Traditional range query methods are mainly aimed at one-dimensional data, and require more uploaded information at perception nodes, resulting in high energy consumption.Therefore, a multi-dimensional data range query method for two-layer wireless sensor

Generic text-based compression models are simple and fast but there are two issues that needs to be addressed. They cannot leverage the structure that exists in data to achieve better compression and there is an unnecessary decompression step before the

Compressed Indexing for Consecutive Occurrences
The fundamental question considered in algorithms on strings is that of indexing, that is, preprocessing a given string for specific queries. By now we have a number of efficient solutions for this problem when the queries ask for an exact occurrence of a given pattern $P$.
