| Abstract | Due to stochastic nature, the success of evolutionary methodologies in search for solutions to optimization problems depends greatly on the harmonization between exploration and exploitation. However, the difficulties in compromising on these two properties properly make the design of an efficient evolutionary algorithm (EA) become one of the laborious tasks. In this paper, a novel EA based on a dynamic system model is proposed. The algorithm composes two evolutionary stages, namely attraction and mutation. Using information about location and fitness of the best individual within the current population, the attraction stage guides candidate solutions toward new locations closer to the best according to a dynamic-system-model-based guidance technique, which is designed to be favorable for exploitation yet retain local diversity. In an opposite manner, the mutation stage, whose role is much the same as in many other EAs, probabilistically changes the values of individuals' elements so as to increase the population diversity and promote the exploration of potential search areas. An early version of the proposed approach was applied to real-valued optimization on a number of benchmark functions. Preliminary results demonstrate that the algorithm is promisingly effective in finding near-optimal solutions to problems where a trade-off between the exploration and exploitation is a must. |

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.
