Abstract | In order to improve the performance of particle swarm optimization, one immune simplex PSO is proposed in the paper. Firstly, orthogonal principle is applied to the initialization of particle, so particles are evenly distributed. Secondly, during the evolution, clone and mutation operation based on fitness evaluation is applied to the particle under the concept of immune. Thirdly, because the value of velocity is close to 0 when the particle is in local optimization, the velocity of the particle is also modified after resetting the position according to the simplex principle. It is verified by multidimensional, nonlinear function (Grievank function) in MATLAB. The result shows that the improved PSO can realize global optimization effectively. And in order to analyze the static characteristic of engine effectively, the paper first transforms the nonlinear equations describing engine system characteristics into optimization problem. Then, the improved PSO proposed in the paper is applied to solve the nonlinear and multidimensional problem. The result shows that the improved PSO can analyze effectively. |

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.
