| Abstract | In many problems, the quality of solutions and computational effort required by optimization algorithms can be improved by exploiting knowledge found in the linkages or interrelations between problem dimensions or components. These linkages are sometimes known a priori from the nature of the itself; in other cases linkages can be learned by sampling the data space prior to the application of the optimization algorithm. This paper presents a new version of the particle swarm optimization algorithm (PSO) that utilizes linkages between components, performing more frequent simultaneous updates on subsets of particle position components that are strongly linked. Prior to application of this linkage-sensitive PSO algorithm, problem specific linkages can be learned by examining a randomly chosen collection of points in the search space to determine the correlations in fitness changes resulting from perturbations in pairs of components of particle positions. The resulting algorithm, adaptive-linkage PSO (ALiPSO) has performed significantly better than the classical PSO, in simulations conducted so far on several test problems. |

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.
