Analysis of a new skip list variant [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2006
For a skip list variant, introduced by Cho and Sahni, we analyse what is the analogue of horizontal plus vertical search cost in the original skip list model.

Accessible and Deterministic Automata: Enumeration and Boltzmann Samplers [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2006
We present a bijection between the set $\mathcal{A}_n$ of deterministic and accessible automata with $n$ states on a $k$-letters alphabet and some diagrams, which can themselves be represented as partitions of the set $[\![ 1..(kn+1) ]\!]$ into $n$ non ...

Tree Buffers [PDF]

open access: yes, 2015
In runtime verification, the central problem is to decide if a given program execution violates a given property. In online runtime verification, a monitor observes a program’s execution as it happens.

Explicit computation of the variance of the number of maxima in hypercubes [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2006
We present a combinatorial approach of the variance for the number of maxima in hypercubes. This leads to an explicit expression, in terms of Multiple Zeta Values, of the dominant term in the asymptotic expansion of this variance.Moreover, we get an ...

Shared-memory Graph Truss Decomposition

open access: yes, 2017
We present PKT, a new shared-memory parallel algorithm and OpenMP implementation for the truss decomposition of large sparse graphs. A k-truss is a dense subgraph definition that can be considered a relaxation of a clique. Truss decomposition refers to a

Properties of Random Graphs via Boltzmann Samplers [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2007
This work is devoted to the understanding of properties of random graphs from graph classes with structural constraints. We propose a method that is based on the analysis of the behaviour of Boltzmann sampler algorithms, and may be used to obtain precise

The master ring problem [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2005
We consider the $\textit{master ring problem (MRP)}$ which often arises in optical network design. Given a network which consists of a collection of interconnected rings $R_1, \ldots, R_K$, with $n_1, \ldots, n_K$ distinct nodes, respectively, we need to

Concentration Properties of Extremal Parameters in Random Discrete Structures [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2006
The purpose of this survey is to present recent results concerning concentration properties of extremal parameters of random discrete structures. A main emphasis is placed on the height and maximum degree of several kinds of random trees. We also provide

Reachability Preservers: New Extremal Bounds and Approximation Algorithms

open access: yes, 2023
We abstract and study \emph{reachability preservers}, a graph-theoretic primitive that has been implicit in prior work on network design. Given a directed graph $G = (V, E)$ and a set of \emph{demand pairs} $P \subseteq V \times V$, a reachability ...

Randomized Optimization: a Probabilistic Analysis [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2007
In 1999, Chan proposed an algorithm to solve a given optimization problem: express the solution as the minimum of the solutions of several subproblems and apply the classical randomized algorithm for finding the minimum of $r$ numbers.
