Abstract. In this work we extend a VNS for the periodic vehicle routing problem with time windows (PVRPTW) to a multiple VNS (mVNS) where several VNS instances are applied cooperat...
We describe the design and experiences gained with the database- and web-based document server DOL, which we developed at the University of Leipzig (http://dol.uni-leipzig.de). Th...
Workflow technology has reached a reasonable degree of maturity, with a number of both research prototypes and commercial systems available. However, methodological issues have rec...
Hierarchical algorithms such as multigrid applications form an important cornerstone for scientific computing. In this study, we take a first step toward evaluating parallel lan...
