Trading Static for Adaptive Security in Universally Composable Zero-Knowledge
Adaptive security, while more realistic as an adversarial model, is typically much harder to achieve compared to static security in cryptographic protocol design. Universal composi...

Online Conflict-Free Colorings for Hypergraphs
We provide a framework for online conflict-free coloring (CF-coloring) of any hypergraph. We use this framework to obtain an efficient randomized online algorithm for CF-coloring ...

Distributed Computing with Advice: Information Sensitivity of Graph Coloring
Abstract. We study the problem of the amount of information (advice) about a graph that must be given to its nodes in order to achieve fast distributed computations. The required s...

Affine Systems of Equations and Counting Infinitary Logic
We study the definability of constraint satisfaction problems (CSP) in various fixed-point and infinitary logics. We show that testing the solvability of systems of equations over...

In-Place Suffix Sorting
Given string T = T[1, . . . , n], the suffix sorting problem is to lexicographically sort the suffixes T[i, . . . , n] for all i. This problem is central to the construction of suf...

Efficient Algorithms for Constant Well Supported Approximate Equilibria in Bimatrix Games
Abstract. In this work we study the tractability of well supported approximate Nash Equilibria (SuppNE in short) in bimatrix games. In view of the apparent intractability of constr...

Conservative Ambiguity Detection in Context-Free Grammars
The ability to detect ambiguities in context-free grammars is vital for their use in several fields, but the problem is undecidable in the general case. We present a safe, conser...
