The basic idea is to use a fast one-dimension (1D) reduced filter and a fast two-dimension (2D) reduced filter that remove large amount of false positives and elementary tests between the primitives. The culling method could be combined with other techniques. The algorithm has been implemented and tested on two benchmarks, including cloth-ball simulations and N-body simulations. The results demonstrate that the algorithm can efficiently reduce the number of elementary tests one order of magnitude, and improve the overall performance of collision query about one half.","PeriodicalId":244586,"journal":{"name":"2012 Third World Congress on Software Engineering","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127874961","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 dynamic characteristic of environment causes difficulty to predict and control the act of Agent in software. Well-defined evolution logic is helpful to describe and limit individual behavior of Agent and coordination among Agents. In this paper, in view to dynamic environment, a process of software evolution in this kind of environment is given. In this process, Agent-based Software Evolution Logic Description Language (Agent SELDL) presented in this paper can give a particular description of evolution process and its logic. Finally, the validity of Agent SELDL is proved by an experiment of software evolution process in dynamic environment.","PeriodicalId":244586,"journal":{"name":"2012 Third World Congress on Software Engineering","volume":"2021 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124259275","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}

They have permeated financial sectors, banking sectors, e-business and online shopping. Usually, different users have different permissions on these applications. Additionally, role-based access control (RBAC) mechanisms have been wildly integrated into web applications. The security and correctness of web applications are the most fundamental, crucial aspects to the success of business and organizations. In existing research work on modeling of RBAC, the user's roles and permissions are fixed and static, and do not consider that with the evolution and running of the system, the roles and permissions are dynamic. To the best of our knowledge, research work on role-based access control modeling and testing for web application has been seldom done. In this paper, taking the dynamic feature of roles and permissions into account, we propose an approach to modeling and testing web applications with role-based access control. We give out an algorithm to capture and compute the dynamicity of roles and permissions in running time. The FSM is employed to model the behavior of web applications, and then the augmented FSM (AFSM) is plied as a tool to model role-based access control. Finally, using the construction algorithm, the tests are generated automatically which satisfy the corresponding test coverage criteria.","PeriodicalId":244586,"journal":{"name":"2012 Third World Congress on Software Engineering","volume":"244 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124688162","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 structures of web applications are complex. Furthermore, the interaction features exacerbate their complexity. How to ensure their reliability and quality presents a challenge to software testers. In this paper, according to the features of web applications, we have formally defined and presented intra-page interactions coverage criteria, inter-page interactions coverage criteria, page-server interactions coverage criteria and scenario-based page-server interactions coverage criteria. Based on each of these coverage criteria, using a motivating example, we present a method to generate test sequences.
