Most queries to text search engines are ranked or Boolean. Phrase querying is a powerful technique for refining searches, but is expensive to implement on conventional indexes. I...
To successfully search multiple coadaptive subcomponents in a solution, we developed a novel cooperative evolutionary algorithm based on a new computational multilevel selection f...
Indexing XML is crucial for efficient XML query processing. We propose a compact tree (Ctree) for XML indexing, which provides not only concise path summaries at group level but a...
In this paper, we study the major modules of on-line handwritten chemical expressions recognition. We propose a novel two-level algorithm to recognize expressions. In the first le...

In this paper we study structural properties of SPN ciphers in which both the S-boxes and the affine layers are involutions. We apply our observations to the recently designed Rijn...
