Entity Resolution is the task of mapping the records within a database to their corresponding entities. The entity resolution problem presents a lot of challenges because of the absence of complete information in records, variant distribution of records for different entities and sometimes overlaps between records of different entities. In this paper, we have proposed an unsupervised method to solve this problem. The previously mentioned problem is set as a partitioning problem. Thereafter, an optimization algorithm-based technique is proposed to solve the entity resolution problem. The presented approach enables the partitioning of records across entities. A comparative analysis with the genetic algorithm over datasets proves the efficiency of the considered approach.
Electrodeposition was originally used for the preparation of metallic mirrors and corrosion resistant surfaces. In this paper, we study a stationary one dimensional system modelling nickel-iron alloy electrodeposition. This system takes into consideration the following phenomena: dissociation, diffusion, electromigration, convection and deposition of multiple ion species. In this work, we present the finite element discretization of the main model supported with a numerical algorithm to effectively handle the nonlinearities. We compare the obtained numerical result with experimental data reported in the literature and show that our simulation method can predict the characteristic features of the Nickel-Iron system.
Vehicle routing problems are widely available in real world application. In this paper, we tackle the resolution of a specific variant of the problem called in the literature vehicle routing problem with flexible time windows (VRPFlexTW), when the solution has to obey several other constraints, such as the consideration of travel, service, and waiting time together with time-window restrictions. There are proposed two modified versions of the Multi-objective Adaptive Large Neighbourhood Search (MOALNS). The MOALNS approach and its different components are described. Also it is listed a computational comparison between the MOALNS versions and the Ant colony optimiser (ACO) on a few instances of the VRPFlexTW.
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.
