| Abstract | The problem of constructing optimal test strategy to diagnose permanent faults in electronic and electromechanical systems is considered. The test strategy problem is formulated as an optimal binary decision construction problem, whose solution is known to be NP-complete. Our approach integrates information gain of test into heuristic search methods to subdue the computational explosion of the optimal test strategy problem. Lower bounds of the expected test cost to getting diagnosis information gain are derived. These information-theoretic lower bounds ensure that an optimal solution is found using the heuristic search algorithms, and have enabled us to obtain optimal test strategy. In addition, the algorithms can obtain all optimal test strategies. The effectiveness of the algorithms is demonstrated on several test cases. As a byproduct, our approach to test strategy can be adapted to solve a wide variety of binary decision problems such as medical diagnosis, data base query, quality assurance, and pattern recognition. |

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.
