The budget allocation problem is an optimization problem arising from advertising planning. In the problem, an advertiser has limited budgets to allocate across media, and seeks to optimize the allocation such that the largest fraction of customers can be influenced. It is known that this problem admits a (1 1/e)-approximation algorithm. However, no previous studies on this problem considered a...

MapReduce is one of the programming models for processing large amount of data in cloud where resource allocation is one of the research areas since it is responsible for improving the performance of Hadoop. However the resource allocation can be further improved by focusing on a set of mechanisms, that includes the budget based HFS algorithm where the fast worker node is identified first based...

The quality of a selection decision is a function of the decision rule used and the data collected to support the decision. When physical measurements are the basis of the decision data, the measurement sampling scheme controls measurement uncertainty and influences decision quality. Faced with a fixed experimental budget for measurement collection over multiple attributes, a decision-maker mus...

Many scienti c applications are described through work ow structures. Due to the increasing level of parallelism o ered by modern computing infrastructures, work ow applications now have to be composed not only of sequential programs, but also of parallel ones. Cloud platforms bring on-demand resource provisioning and pay-as-you-go payment charging. Then the execution of a work ow corresponds t...

In this paper we investigate experimentally the effects of a wage tax financed unemployment benefit system on the development of the budget deficit, unemployment, and some other indicators of economic performance in an international economy. We find support for the hypothesis that out-of-equilibrium price uncertainty affects the behavior of economic agents. Due to uncertainty about prices risk-...
