Relative Worst-Order Analysis: A Survey [PDF]

open access: yes, 2018
Relative worst-order analysis is a technique for assessing the relative quality of online algorithms. We survey the most important results obtained with this technique and compare it with other quality measures.Comment: 20 ...

Samples of geometric random variables with multiplicity constraints [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2006
We investigate the probability that a sample $\Gamma=(\Gamma_1,\Gamma_2,\ldots,\Gamma_n)$ of independent, identically distributed random variables with a geometric distribution has no elements occurring exactly $j$ times, where $j$ belongs to a specified

Truss Decomposition in Massive Networks [PDF]

open access: yes, 2012
The k-truss is a type of cohesive subgraphs proposed recently for the study of networks. While the problem of computing most cohesive subgraphs is NP-hard, there exists a polynomial time algorithm for computing k-truss. Compared with k-core which is also

Structure of Stable Sand Piles Model [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2006
In this paper we study a variant of the Sand Piles Model, where the evolution rule consists of the falling down of one grain to a random column and an avalanche to reach a stable configuration.

Density of truth in modal logics [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2006
The aim of this paper is counting the probability that a random modal formula is a tautology. We examine $\{ \to,\Box \}$ fragment of two modal logics $\mathbf{S5}$ and $\mathbf{S4}$ over the language with one propositional variable.

K-core decomposition of Internet graphs: hierarchies, self-similarity and measurement biases [PDF]

open access: yes, 2008
We consider the $k$-core decomposition of network models and Internet graphs at the autonomous system (AS) level. The $k$-core analysis allows to characterize networks beyond the degree distribution and uncover structural properties and hierarchies due ...

Linear time recognition of P4-indifference graphs [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2001
A graph is a P4-indifference graph if it admits an ordering < on its vertices such that every chordless path with vertices a, b, c, d and edges ab, bc, cd has ...

Extracting the hierarchical organization of complex systems

open access: yes, 2007
Extracting understanding from the growing ``sea'' of biological and socio-economic data is one of the most pressing scientific challenges facing us.

Exploiting non-constant safe memory in resilient algorithms and data structures [PDF]

open access: yes, 2015
We extend the Faulty RAM model by Finocchi and Italiano (2008) by adding a safe memory of arbitrary size $S$, and we then derive tradeoffs between the performance of resilient algorithmic techniques and the size of the safe memory.
