A new decision-tree-based multi-objective estimation of distribution algorithm (DT-MEDA) for optimization problems with continuous variables is developed. Decision-tree-based probabilistic models are used to encode conditional dependencies among variables in DT-MEDA. By building and sampling the probabilistic models, the algorithm reproduces the genetic information of the next generation. Incorporating this reproduction mechanism together with the ranking method and the truncated selection, DT-MEDA can approximate the Pareto front. Polynomial mutation operator is used to enhance exploration and maintain diversities in the populations. Furthermore, DT-MEDA adopts a procedure to eliminate a solution with smallest crowding distance at a time in the truncated selection, so that it can obtain a well spread solution set. The performance of the proposed algorithm is evaluated on four biobjective test problems and metrics from literature. Simulation results show that the proposed approach is competitive with NSGA-II and DT-MEDA is a general and effective method for multi-objective optimization.
Abstract. The Future Internet as a design conception is network and serviceaware addressing social and economic trends in a service oriented way. In the Future Internet, applications transcend disciplinary and technology boundaries following interoperable reference model(s). In this paper we discuss issues about federated management targeting information sharing capabilities for heterogeneous infrastructure. In Future Internet architectures, service and network requirements act as design inputs particularly on information interoperability and cross-domain information sharing. An inter-operable, extensible, reusable and manageable new Internet reference model is critical for Future Internet realisation and deployment. The reference model must rely on the fact that highlevel applications make use of diverse infrastructure representations and not use of resources directly. So when resources are not being required to support or deploy services they can be used in other tasks or services. As implementation challenge for controlling and harmonising these entire resource management requirements, the federation paradigm emerges as a tentative approach and potentially optimal solution. We address challenges for a future Internet Architecture perspective using federation. We also provide, in a form of realistic implementations, research results and solutions addressing rationale for federation, all this activities are developed under the umbrella of federated management activity in the Future Internet.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
