The QoS based route optimization is a key issue of the wireless network, which is a NPC-hard multi-objective discrete optimization problem. In this paper, an efficient multi-objective artificial bee colony optimization algorithm based on Pareto dominance called MOABC is proposed to tackle this problem. The algorithm was evaluated on a set of different scale test problems and compared with GA based...
To select a suitable neighborhood size for manifold learning algorithms efficiently, a new method based on BIC (Bayesian Information Criterion) is used in this paper. Due to the locally Euclidean property of the manifold, the PCA (Principal Component Analysis) reconstruction errors of the neighborhoods without shortcut edges remain small; however, those of the neighborhoods with shortcut edges are...
Recently, with the rapid spread of computer technology, XML has become the standard for data exchange for a wide variety of applications. A large number of XML and XML schema are generated by different individual or company. The problem addressed in this paper is the execution of XML queries over multiple XML documents. In this paper, we propose an algorithm: SMXQA (semantics based multi-XML query...
The efficiency of alarm mining in large scale network is a hot topic in research area of fault location. Many projects have been utilized to improve it and some advance has been achieved, but it is still not very satisfied. Large scale telecom system daily generates large numbers of original alarm records and many of them are redundant information, actually useful information for fault location is...
