The issues of coalition formation have been investigated from many aspects and recently more and more attention has been paid to overlapping coalition formation. The (optimal) coalition structure generation(CSG) problem is one of the essential problems in coalition formation which is an important topic of cooperation in multiagent system. In this paper, we strictly define the coalition structure generation...
Constellation networking is the prominent technology for the next generation satellite systems. The communication schedule is a key problem for constellation maintenance. However, the traditional SRS (Satellite Range Scheduling) model do not use inter-satellite links. In this paper, a communication scheduling model is proposed, in which the ISLs (Inter Satellite Links) is built. And the NP complicity...
In our previous works, based on characteristics of emergency systems such as quick response to emergencies, a polynomial time algorithm was proposed to solve task schedulable problem. However, the above mentioned task scheduling method did not consider importance and urgency differences among tasks in selecting task to accomplish. In order to make the task scheduling be more close to actual process...
Diversity maintenance of solutions is a crucial part in multi-objective optimization. However, most of existing studies show a good distribution with a large computational load or a comparative bad distribution quickly. In this paper, a method for pruning a set of non-dominated solutions using a spanning tree is proposed. This approach defines a density estimation metric - spanning tree crowding distance...
Automated trust negotiation is an approach to establish trust in pervasive computing environment, where the involved participators belong to different security domains and need to establish trust before interactions can take place. However, during the trust negotiation, onepsilas private information can be easily exploited to infer through observing onepsilas behavior, even if access control policies...
With the continuing increase in density of VLSI, limited buffer can be placed inside the crossbar and this combined input-crosspoint-queued (CICQ) switch structure decouples the inputs and outputs matching. In this paper, an analysis of the performance of Round-Robin scheduling algorithm for CICQ switch has been made proves that the Round-Robin algorithm can achieve 100% throughput under uniform traffic...
In this paper the client specific kernel discriminant analysis (CSKDA) is studied. The theory of CSKDA, which is the nonlinear model of the previously suggested model of client specific linear discriminant analysis, is proposed by using kernel technique. A new CSKDA subspace method is developed in order to reduce the computational complexity. Results of experiments conducted on the internationally...
