We consider a weekly locomotive scheduling problem encountered at Swedish State Railways. The objective is to find cyclic locomotive schedules, which minim...

The long term analysis of an energy-environment system is fraught with various uncertainties. Classical stochastic programming has been used with large scal...

In many medical experiments data are collected across time, over a number of similar trials or a number of experimental units. As is the case of neural spik...

In this paper we derive a law of the logarithm establishing the exact rate of uniform convergence for nearest neighbor kernel estimators of the density and ...

The three-stage cutting stock problem consists in laying out a set of ordered rectangular pieces on some rectangular strips, and then these strips are laid ...

A hypergraph <i>H=(X,E)</i> is <i>nested</i> if its edges are pairwise disjoint or included one into the other. The <i>nesticity</i> of <i>H</i> is defined...

We consider the problem of inferring evolutionary trees. We propose a quartet reconstruction method which specifically produces trees whose edges have stron...
