| Abstract | Some discrete event systems such as software are typically infinite state systems, and a commonly used technique for performing formal analysis such as automated verification is based on their finite abstractions. In this paper, we consider a model for reactive untimed infinite state systems called input-output extended finite automaton (I/O-EFA), which is an automaton extended with discrete variables such as inputs, outputs, and data. Using I/O-EFA as a model many value-passing processes can be represented by finite graphs. We study the problem of finding a finite abstraction that is bisimilar to a given I/O-EFA. We present a sufficient condition under which the underlying transition system of an I/O-EFA admits a finite bisimilar quotient. This sufficient condition is existential as it relies on the existence of a suitable partition of the state space. We then identify a class of I/O-EFAs for which a partition satisfying our sufficient condition can be constructed by inspecting the structure of the given I/O-EFA |

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.
