Abstract | Conventional methods of determining Pareto dominance in multi-objective optimization evaluate and compare objective vectors of candidate solutions, but the computation and (or) experiment of evaluating objective vectors are overwhelmingly costly when computationally expensive multi-objective problems are involved. This study investigates a nearest neighbor prediction method of Pareto dominance using general regression neural networks (GRNN). The decision differential value (D-value) vector of two feasible solutions is used as the input of GRNN, and the objective D-value vector is used as the output. Under the supervision of sample candidate solutions, GRNN is used to predict objective D-value vectors between an observed solution and samples. For an observed candidate, the predicted objective D-Value vectors are used to find out the nearest neighbor samples in objective space. Experimental results show that the nearest neighbor prediction of Pareto dominance relationships using GRNN can obtain acceptable prediction accuracy. The proposed algorithm provides an effective method to relieve the curse of computation cost in computationally expensive multi-objective optimization problems, but without requirement for analytical models of objective functions. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
