| Abstract | A Rao-Blackwellized particle filter (RBPF) approach is an effective means to estimate the full SLAM posterior. To improve the memory efficiency of RBPF-SLAM, our previous work proposed a SLAM framework based on Rao-Blackwellised particle filters (RBPF) and genetic algorithms (GA) for recovering the full SLAM posterior using raw exteroceptive sensor measurements, i.e. without landmarks. The resultant Rao-Blackwellised genetic algorithmic filter SLAM (RBGAF-SLAM) permits the efficient use of any arbitrary measurement model. However, the drawback is that the GA operators have to be determined heuristically and the parameters have to be tuned through try-and-error. These tuning operations are time consuming and the optimized solution is not guaranteed. In this paper, we provide the detailed description of how to optimize the RBGAF-SLAM operators through genetic learning approach. GA operators and parameters are encoded into chromosomes, while the Euclidian localization error is chosen to build the fitness function. This approach guarantees the consistent SLAM results and ensures the global convergence to the optimal solution of RBGAF-SLAM. Simulations and experimental data are used as training data. A robot with laser range scanner is used to demonstrate the effectiveness in actual implementations. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
