Imbalance Is Fixed Parameter Tractable
In the Imbalance Minimization problem we are given a graph G = (V, E) and an integer b and asked whether there is an ordering v1 . . . vn of V such that the sum of the imbalance of...

Tracking a Generator by Persistence
The persistent homology provides a mathematical tool to describe “features” in a principled manner. The persistence algorithm proposed by Edelsbrunner et al. [9] can compute n...

Faster Generation of Shorthand Universal Cycles for Permutations
A universal cycle for the k-permutations of n = {1, 2, ..., n} is a circular string of length nk that contains each k-permutation exactly once as a substring. Jackson (Discrete Mat...

Clustering with or without the Approximation
We study algorithms for clustering data that were recently proposed by Balcan, Blum and Gupta in SODA’09 [4] and that have already given rise to two follow-up papers. The input f...

Identity-Based Authenticated Asymmetric Group Key Agreement Protocol
In identity-based public-key cryptography, an entity’s public key can be easily derived from its identity. The direct derivation of public keys in identity-based public-key crypt...

A K-Provers Parallel Repetition Theorem for a Version of No-Signaling Model
The parallel repetition theorem states that for any two provers one round game with value at most 1 − (for < 1/2), the value of the game repeated n times in parallel is at mo...

Detecting Areas Visited Regularly
We are given a trajectory T and an area A. T might intersect A several times, and our aim is to detect whether T visits A with some regularity, e.g. what is the longest time span t...

A Polynomial-Time Perfect Sampler for the Q-Ising with a Vertex-Independent Noise
We present a polynomial-time perfect sampler for the Q-Ising with a vertex-independent noise. The Q-Ising, one of the generalized models of the Ising, arose in the context of Baye...
