We describe a hybrid meta-heuristic algorithm for combinatorial optimization problems with a specific reference to the travelling salesman problem (TSP). The method is a combination of a genetic algorithm (GA) and greedy randomized adaptive search procedure (GRASP). A new adaptive fuzzy a greedy search operator is developed for this hybrid method. Computational experiments using a wide range of...

Material properties and geometry are two important design parameters which their effects should be considered in a crashworthiness analysis. In this paper, the axial impact of metallic and hybrid energy absorbing thin-walled tubes with poly-gonal cross-section is simulated using LS-DYNA software. The combined effects of changing the geometry and material properties on the mass specific energ...

Abstract: Enabling the inter-domain routing with end-to-end Quality of Service (QoS) guarantees, remains a challenge for the next generation Internet. Most of the existing research in QoS routing has been done considering a single domain. However, extending the QoS routing to the inter-domain level faces two major challenges: the scalability and the domain autonomy. In this paper, we propose a ...

Mashup environments enable end users to directly engage in the design process of the information system. Traditional mashup technology offers users generic components and therefore targets technically skilled people. Recent research investigates domain-specific mashup platforms with the aim to be easier to understand and use. We present a proposal for research towards a generic framework that s...

In the context of a hybrid French-toEnglish SMT system for translating online forum posts, we present two methods for addressing the common problem of homophone confusions in colloquial written language. The first is based on hand-coded rules; the second on weighted graphs derived from a large-scale pronunciation resource, with weights trained from a small bicorpus of domain language. With auto...
