ORBi Open Repository and Bibliography (263.678 recursos)

In may 2007, the ULg's Administrative Board (joined in June 2007 by the FUSAGx) decided to create an institutional repository and defined a strong institutional self-archiving policy to increase the visibility, accessibility and impact of the University's publications (Board's decision). This decision led to the official launch, in November 2008, of the ORBi platform including both the Academic Bibliography and the Institutional Repository of the Wallonia-Europe University Academy.

  2. Balanced words and related concepts: applications and complexity issues

    Crama, Yves
    In this talk, I present a few results and several questions about "regular" sequences of integers and related concepts, such as balanced words, partitions and covers of the integers by arithmetic sequences. Such concepts have been investigated in pure mathematics, but also naturally arise in a variety of application fields such as production planning, political science, or queueing theory. I briefly present some of these applications and explain how they motivate seemingly new questions relating, for instance, to the algorithmic complexity of regular partitions, or to the structure of balanced words. The presentation is based on joint work with Nadia Brauner and Vincent Jost (Grenoble).

  8. Quadratic reformulations of nonlinear binary optimization problems

    Crama, Yves
    A {\em pseudo-Boolean function} is a real-valued function $f(x)=f(x_1,x_2,\ldots,x_n)$ of $n$ binary variables, that is, a mapping from $\{0,1\}^n$ to $\mathbf R$. \emph{Nonlinear binary optimization problems} of the form \begin{equation}\label{eq:PBO} \min \{ f(x) : x \in \{0,1\}^n \}, \end{equation}, where $f$ is a pseudo-Boolean function expressed as a multilinear polynomial in its variables, are notoriously difficult. For a pseudo-Boolean function $f(x)$ on $\{0,1\}^n$, we say that $g(x,y)$ is a \emph{quadratization} of $f$ if $g(x,y)$ is a quadratic polynomial depending on $x$ and on $m$ \emph{auxiliary} binary variables $y_1,y_2,\ldots,y_m$ such that $f(x)= \min \{ g(x,y) : y \in \{0,1\}^m \} $ for all $x \in...
