Parameterized Complexity and Kernelizability of Max Ones and Exact Ones Problems
For a finite set Γ of Boolean relations, Max Ones SAT(Γ) and Exact Ones SAT(Γ) are generalized satisfiability problems where every constraint relation is from Γ, and the task...

A Fast and Low Complexity Image Codec based on Backward Coding of Wavelet Trees
A new approach of backward coding of wavelet trees (BCWT) is presented. Contrary to the common “forward” coding of wavelet trees from the highest level (lowest resolution), th...

Dispersion of Mass and the Complexity of Randomized Geometric Algorithms
How much can randomness help computation? Motivated by this general question and by volume computation, one of the few instances where randomness provably helps, we analyze a noti...

On the complex behavior of simple tag systems - An experimental approach
It is a well-know fact that apparently simple systems can give rise to complex behavior. But why exactly does a given system behave in a complex manner? There are two main approac...
