Recently, there have been many improvements for the computation of Tate pairing, which focuses on the arithmetical operations above the finite field. In this paper, we analyze the structure of Miller’s algorithm firstly, which is used to implement Tate pairing. Then, according to the characteristics that Miller’s algorithm will be improved tremendous if the order of the subgroup of elliptic curve group is low hamming prime, we present an effective generation method of elliptic curve using the Fermat number, which enable it feasible that there is certain some subgroup of low hamming prime order in the elliptic curve group generated. Finally, we give an example to generate elliptic curve, which includes the subgroup with low hamming prime order. It is clear that the computation of Tate pairing above elliptic curve group generating by our method can be improved tremendously.","PeriodicalId":34860,"journal":{"name":"HumanMachine Communication Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83967306","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A dynamic direction restricted searching algorithm is presented, based on the Dijkstra algorithm for computing shortest path from one node to another node in road net. In comparison with classic Dijdstra algorithm, the searching algorithm, combined with human searching thought and flexible handle, could change restricted area dynamically and save computation time. The efficiency of computing shortest path was improved by this algorithm only and better effects were given when this algorithm was combined with other algorithms. The results of comparative experiments show that the dynamic direction restricted searching algorithm led to almost a saving ratio of 50 %, in terms of both number of nodes selected and computation times.","PeriodicalId":34860,"journal":{"name":"HumanMachine Communication Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84767583","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The key problem in cluster ensemble is how to combine multiple clusterings to yield a final superior result. In this paper, an Improved Non-negative Matrix Factorization (INMF) algorithm is proposed. Firstly, K-Means algorithm is performed to partition the hypergraph’s adjacent matrix and get the indicator matrix, which is then provided to NMF as initial factor matrix. Secondly, NMF is performed to get the basis matrix and coefficient matrix. Finally, clustering result is obtained via the elements in coefficient matrix. Experiments on several real-world datasets show that: (a) INMF outperforms the NMF-based cluster ensemble algorithm; (b) INMF obtains better clustering results than other common cluster ensemble algorithms.","PeriodicalId":34860,"journal":{"name":"HumanMachine Communication Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90061195","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Then according to the partial order relation, the individuals are sorted for generating the non-dominated individuals. Moreover, to enhance the evolution’s ability, some individuals are evolved in the same generation and the crossover operate by Cauchy Distribution is adopted. In addition, non-dominated individuals generated in each generation are archived to Pareto set filter to reserve all individuals with good characteristic generated in the evolving process. Finally, some Benchmark functions are used to test the algorithm performance.
