    Solving Hard Multiobjective Problems with a Hybridized Method

    This paper presents a hybrid method to solve hard multiobjective problems. The proposed approach adopts an epsilon-constraint method which uses a Particle Swarm Optimizer to get points near of the true Pareto front. In this approach, only few points will be generated and then, new intermediate points will be calculated...

    An MDA Approach to Business Process Model Transformations

    The authors present in this paper an MDA approach for the definition of transformations for business process models. These transformations are based on the use of two platform independent workflow universal languages - UML 2.0 Activity Diagrams and BPMN - and a platform specific language, the XPDL language. The first...

    Metric-Temporal Access Methods

    Metric-temporal databases are a new database model that combines metric spaces with temporal databases to process similarity queries within a time interval or snapshot. The Historical FHQT is a metric-temporal index which has shown to be competitive answering this type of queries. This index store a list of valid snapshots...
