We introduce NeighborNet, a network construction and data representation method that combines aspects of the neighbor joining (NJ) and SplitsTree. Like NJ, NeighborNet uses agglomeration: taxa are combined into progressively larger and larger ...

My anthropological analysis of bionics is based on the representations of engineers concerning the definition of humankind and its future. The difference between repairing and improving on human beings is disappearing and we strive to reach a kind of `...

We consider an optimal shape design problem of grapple loaders. Our aim is to minimize the weight of the machine. The durability is taken into account via stress and buckling constraints. Thus we have a nonlinear and nonconvex constrained optimization ...

This paper describes the parallelization of a two-phase metaheuristic for the vehicle routing problem with time windows and a central depot (VRPTW). The underlying objective function combines the minimization of the number of vehicles in the first ...

In this paper we study both theoretically and experimentally some properties of classical linear systems solvers, according to the radiosity assumptions. We prove important properties for some of these solvers, which allow the user to choose the best ...

Gegenstand des Beitrags ist die Entwicklung eines genetischen Tourenplanungsalgorithmus. Zunächst wird ein einfacher Genetischer Algorithmus (GA) für das mengen- und streckenmäβig restringierte Standardproblem mit einem Depot vorgestellt. Anschlies βend ...
