The amount of Internet sales has been growing at a high and constant rate over the last years. Many customers use Internet shops on a regular basis. Internet shops ensure a high transparency on product properties (including prices) and customers are able to easily compare a large number of...

While in the past decades research on multi-objective evolutionaryalgorithms (MOEA) has aimed at finding the wholeset of Pareto optimal solutions, current approaches focus ononly those parts of the Pareto front which satisfy the preferencesof the decision maker (DM). Therefore, they integratethe...

Until recently, multidimensional knapsack problems (MDKP)and winner determination problems (WDP) have been studiedindependently of each other, although WDPs can bemodelled as MDKPs. State-of-the-art optimization methodsfor WDPs are exact algorithms whereas MDKPs aremainly solved using heuristics...

The understanding of human behavior in sequential decision tasks is important for economics and socio-psychological sciences. In search tasks, for example when individuals search for the best price of a product, they are confronted in sequential steps with different situations and they have to...

This paper considers the optimal communication spanning tree (OCST) problem. Previouswork analyzed features of high-quality solutions and found that edges in optimal solutions havelow weight and point towards the center of a tree. Consequently, integrating this problem-specific knowledge into a...
