Polynomial algorithms for partitioning a tree into single-center subtrees to minimize flat service costs
(Wiley, 2008)
This paper deals with the following graph partitioning problem. Consider a connected graph with n nodes, p of which are centers, while the remaining ones are units. For each unit-center pair there is a fixed service cost ...

Production-inventory games and PMAS-games: characterizations of the Owen point
(Elsevier, 2008)
Production-inventory games were introduced in [Guardiola, L.A., Meca, A., Puerto, J. (2008). Production-Inventory games: A new class of totally balanced combinatorial optimization games. Games Econom. Behav. doi:10.1016/ ...

Partially ordered cooperative games: extended core and Shapley value
(Springer, 2008-02)
In this paper we analyze cooperative games whose characteristic function takes values in a partially ordered linear space. Thus, the classical solution concepts in cooperative game theory have to be revisited and redefined: ...

Center location problems on tree graphs with subtree-shaped customers
(Elsevier, 2008-08-06)
We consider the p-center problem on tree graphs where the customers are modeled as continua subtrees. We address unweighted and weighted models as well as distances with and without addends. We prove that a relatively ...

Optimal expected-distance separating halfspace
(INFORMS (Institute for Operations Research and Management Sciences), 2008-08)
One recently proposed criterion to separate two datasets in discriminant analysis, is to use a hyperplane which minimises the sum of distances to it from all the misclassified data points. Here all distances are supposed ...

A generalized model of equality measures in network location problems
(Elsevier, 2008-03)
In this paper, the concept of the ordered weighted averaging operator is applied to define a model which unifies and generalizes several inequality measures. For a location x, the value of the new objective function is the ...

Dimensionality Reduction for Classification: Comparison of Techniques and Dimension Choice
(Springer, 2008)
We investigate the effects of dimensionality reduction using different techniques and different dimensions on six two-class data sets with numerical attributes as pre-processing for two classification algorithms. Besides ...
