Improving Semistatic Compression Via Pair-Based Coding
In the last years, new semistatic word-based byte-oriented compressors, such as Plain and Tagged Huffman and the Dense Codes, have been used to improve the efficiency of text retri...

Efficient Algorithms for Computing the Nearest Polynomial with Constrained Roots
Continuous changes of the coefficients of a polynomial move the roots continuously. We consider the problem finding the minimal perturbations to the coefficients to move a root to...

Efficient Continuous Skyline Computation
In a number of emerging streaming applications, the data values that are produced have an associated time interval for which they are valid. A useful computation over such streami...

Efficient Computation of Adaptive Threshold Surfaces for Image Binarization
The problem of binarization of gray level images acquired under nonuniform illumination is reconsidered. Yanowitz and Bruckstein proposed to use for image binarization an adaptive...

The Effect of Flexible Parsing for Dynamic Dictionary Based Data Compression
We report on the performance evaluation of greedy parsing with a single step lookahead, denoted as flexible parsing. We also introduce a new fingerprint based data structure which...
