In this paper we deal with the Internet Shopping Optimization Problem. An extended model that includes price sensitive discounts is considered. A set of algorithms to solve the Internet Shopping Optimization Problem with Price Sensitivity Discounts (ISOPwD) is introduced. The algorithms are designed to consider a different solution quality regarding computational time and results close to the optimum...
There are an increasing number of high-performance networks that provision dedicated channels through circuit-switching or MPLS/GMPLS techniques to support bulk data transfer in large-scale science or e-commerce applications. These dedicated links are typically shared by multiple users through advance reservations, resulting in varying bandwidth availability in future time periods. Therefore, efficient...
RSA is the most widely used digital signature algorithm in e-commerce and the complexity of large integer operation is the main factor that affects the efficiency of a RSA system. In this paper, a n carry array based large integer denotation approach is proposed to speed up the large integer calculation in RSA key generation and data encryption/decryption process, so as to improve the efficiency of...
