| Abstract | This paper presents the implementation of particle filter (PF) combined with a coevolution mechanism derived from the competition model of ecological species for mobile robot simultaneous localization and mapping (SLAM). The new version of particle filters is termed coevolution particle filter (CEPF). In CEPF particles are clustered into species, each of which represents the posterior estimation of robot's pose or landmark locations and is superior to a single particle. Since the coevolution between the species ensures that the multiple distinct hypotheses can be estimated at the same time. And the number of particles can be adjusted adaptively over time according to the population growth model. In addition, by using the crossover and mutation operators in evolutionary computation, intra-species evolution can drive the particles move towards the regions where the desired posterior density is large. So a small number of particles can represent the desired density well enough to make precise posterior estimation. Experimental results show that CEPF is efficient for SLAM and indicate superior performance compared with those of the EKF and PF method. |

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.
