A Comparison of Algorithms for the Multivariate L1-Median

Fritz, H.; Filzmoser, P.; Croux, C. - Tilburg University, Center for Economic Research - 2010

computing the L1- median are available. Problem speci c algorithms can be used, but also general optimization routines. The aim … algorithms have been implemented in a standardized manner in the open source environment R. In most sit- uations, the algorithm … based on the optimization routine NLM (non- linear minimization) clearly outperforms other approaches. Its low computation …

Processing Games with Shared Interest

Quant, Marieke; Reijnierse, Hans; Meertens, M. - Tilburg University, Center for Economic Research - 2004

A generalization of processing problems with restricted capacities is introduced.In a processing problem there is a finite set of jobs, each requiring a specific amount of effort to be completed, whose costs depend linearly on their completion times.The new aspect is that players have interest...

On a New Class of Parallel Sequencing Situations and Related Games

Borm, Peter; Calleja, P.; Hamers, H.J.M.; Klijn, F. - Tilburg University, Center for Economic Research - 2001

This paper considers a special class of sequencing situations with two parallel machines in which each agent has precisely two jobs to be processed, one on each machine.The costs of an agent depend linearly on the final completion time of his jobs.We describe a procedure that provides an optimal...

Processing Games with Restricted Capacities

Borm, Peter; Reijnierse, Hans; Quant, Marieke; Meertens, M. - Tilburg University, Center for Economic Research - 2004

This paper analyzes processing problems and related cooperative games.In a processing problem there is a finite set of jobs, each requiring a specific amount of effort to be completed, whose costs depend linearly on their completion times.There are no restrictions whatsoever on the processing...

Optimal Tax Depreciation Lives and Charges under Regulatory Constraints

De Waegenaere, Anja; Wielhouwer, J.L. - Tilburg University, Center for Economic Research - 2001

Depreciation is not only a representation of the loss in asset-value over time.It is also a strategic tool for management and can be used to minimize tax payments.In this paper we derive the depreciation scheme that minimizes the expected value of the present value of future tax payments for two...

Intersection theorems with a continuum of intersection points

Talman, Dolf; Herings, P.J.J. - Tilburg University, Center for Economic Research - 1994

In all existing intersection theorems conditions are given under which acertain subset of acollection of sets has a non-empty intersection. In this paper conditions are formulated under which the intersection is a continuum of points satisfying some interesting topological properties. In this...
