| Abstract | This paper proposes a parallel particle swarm optimization (PPSO) to solve the multiobjective optimization problems (MOP). PPSO makes the use of the parallel characteristic of the PSO algorithm to deal with the multiple objectives issue of the MOP. PPSO uses as many swarms as the number of the objectives in the MOP and lets each swarm optimize only one of the objectives. These swarms work in parallel and each swarm can use a standard PSO or any other improved PSO variants to solve a single objective problem. PPSO has advantages on the following two aspects. First, as each swarm focus on optimizing only one objective, PPSO can avoid the difficulty of fitness assignment because the particles can be evaluated like in the single objective optimization problem. Second, as different swarms optimize different objectives, PPSO can maintain the population diversity to make a throughout search along the whole Pareto front to obtain nondominated solutions as many as possible. The performance of PPSO is tested on a set of benchmark problems complicated Pareto sets in CEC2009. The experimental results compared with those obtained by the state-of-the-art algorithms demonstrate the effectiveness and efficiency of PPSO, showing the good performance of PPSO in solving the MOP with complicated Pareto sets. |

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.
