trust relationship plays an important role in helping customers arrive at a trade decision in e-commerce. Numerous models and prediction algorithms have been proposed to calculate trust value. However, these models and algorithms are impractical in e-commerce transaction. In this paper, customer-to-customer and customer-to-commodity trust relationship sub-networks are proposed to get clear trust network which can be maintained easily. trust relationships are divided into three types which are functional trust, referral trust and latent trust. We propose a trust algorithm to compute the trust value of customer-to-commodity trust which can help customers to make final purchase decisions directly. Our algorithm is based on more comprehensive trust features such as the referral trust, latent trust, domain similarity of Web commodities that users are interested in, and the influence of different reputations of users within two sub-networks. Experiment results with data sets from *** illustrate more accurate trust prediction compared with those existed algorithms.

Firstly, a multilevel trust algorithm for MANET （mobile ad hoe networks） is presented in this paper and the trust level is defined as a three-tuple type in this multilevel trust algorithm. The paper introduces the multilevel trust into MANET, thereby controlling restricted classified information flows among nodes that have different trust levels. Secondly, the infrastructure of MANET that suit to our multi-level trust is presented, Some conclusions are given at lastly.

Based on the concept of subenergy transformation and the terminal repeller in the terminal repeller unconstrained subenergy tunneling (trust) algorithm, a global optimization algorithm, called the random tunneling algorithm (RTA), is proposed. RTA is a two-phase optimization method in which a global phase is carried out by random tunneling and a local phase by gradient optimization with the BFGS method. In RTA, the population of start points is generated randomly, and the similarity checking is performed during the cycles of the two phases. RTA was compared with other well-known stochastic methods in the optimization of the standard test functions. The potential energy function of Lennard-Jones clusters was also selected as an instance to investigate the performance of the RTA in high-dimensional optimization. All the global minima of LJ clusters containing up to 100 atoms were successfully located. The results indicate that RTA may be a good tool for the structural optimization problem.
