Regular Expression Searching over Ziv-Lempel Compressed Text
We present a solution to the problem of regular expression searching on compressed text. The format we choose is the Ziv-Lempel family, speci cally the LZ78 and LZW variants. Give...

Hybrid Logics on Linear Structures: Expressivity and Complexity
We investigate expressivity and complexity of hybrid logics on linear structures. Hybrid logics are an enrichment of modal logics with certain first-order features which are algo...

An Evolutionary Algorithm for Optimization of Pseudo Kronecker Expressions
—Using EXOR gates in logic synthesis often results in smaller circuit realizations. While in AND/OR synthesis the problem definition is clear, in AND/EXOR synthesis several clas...

Some Aspects of Parsing Expression Grammar
Parsing Expression Grammar (PEG) is a new way to specify syntax, by means of a top-down process with limited backtracking. It can be directly transcribed into a recursive-descent ...

Hardness of Minimizing and Learning DNF Expressions
We study the problem of finding the minimum size DNF formula for a function f : {0, 1}d → {0, 1} given its truth table. We show that unless NP ⊆ DTIME(npoly(log n) ), there i...
