Our link removal for single application mainly includes iterative link removal selection algorithm based on low link utilization for topology optimization and turn model based deadlock free routing algorithm for irregular 2D Mesh with reduced links. In addition, we also consider multiapplication from realistic requirement and try to define various execution modes. The seamless combination of multiapplications and link removal method is achieved via corresponding interoperation of removed link set. Taking typical media applications VOPD and MWD for example, the simulation results verify proposed multi-application specified NoC link removal strategy valid for area cost optimization and acceptable performance degradation.","PeriodicalId":210815,"journal":{"name":"2011 Fourth International Joint Conference on Computational Sciences and Optimization","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134150998","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}

This paper developed a novel method integrating support vector machine (SVM) with copula function. Different from existing single-factor or bifactor pricing models based on corporate value and the underlying stock price respectively, this model can effectively deal with many constrains on the CB pricing, such as nonlinearity, departure from normality, multivariate joint distribution, variable dependence structure, and so on. In particularly, the new model exhibited great flexibility in that copula function can portray dependence structure between the underlying stock price and interest rate, and that SVM can further tackle nonlinear relationship among variables. Empirical analysis showed that the proposed model enhanced generation ability of out-of-sample, with mark increase in CB pricing accuracy compared with the single SVM, and that the CB value sensitivity to the underlying stock and the dependence structure is also measured handily and effectively through the model.","PeriodicalId":210815,"journal":{"name":"2011 Fourth International Joint Conference on Computational Sciences and Optimization","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134593590","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}

This algorithm is based upon the use of Genetic Algorithm techniques. The algorithm employs a roulette wheel based selection mechanism, the use of a survival-of-the-fittest strategy, a heuristic crossover operator, and an inversion operator. To illustrate it more clearly, a program based on this algorithm has been implemented, which presents the changing process of the route iteration in a more intuitive way. Finally, we apply it into a TSP problem with fifty cities. By comparing with other published techniques, we can easily know that the proposed algorithm can efficiently complete the search process and derive a better solution.","PeriodicalId":210815,"journal":{"name":"2011 Fourth International Joint Conference on Computational Sciences and Optimization","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114217041","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 quantitive mathematical model of the weight influencing factor was built, and a directed acycline graph with weight was generated by combining the function's control flow chart. Further more, the tested function's critical path was given by the algorithm based on AOE-net. After a test case was done, the hypo-critical path was chosen until the test criterion was guaranteed. The experiment results showed that with a scheduled test time among modules, the software test efficiency was improved achieving the objective of software quality assurance(SQA).","PeriodicalId":210815,"journal":{"name":"2011 Fourth International Joint Conference on Computational Sciences and Optimization","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114467504","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}
