| Abstract | Existing reachability analysis techniques are easy to fail when applied to large compositional linear hybrid systems, since their memory usages rise up quickly with the increase of systems' size. To address this problem, we propose a tool BACH 2 that adopts a path-oriented method for bounded reachability analysis of compositional linear hybrid systems. For each component, a path is selected and all selected paths compose a path set for reachability analysis. Each path is independently encoded to a set of constraints while synchronization controls are encoded as a set of constraints too. By merging all the constraints into one set, the path-oriented reachability problem of a path set can be transformed to the feasibility problem of this resulting linear constraint set, which can be solved by linear programming efficiently. Based on this path-oriented method, BACH 2 adopts a shared label sequence guided depth first search (SLS-DFS) method to perform bounded reachability analysis of compositional linear hybrid system, where all potential path sets within the bound limit are identified and verified one by one. By this means, since only the structure of a system and the recently visited one path in each component need to be stored in memory, memory consumption of BACH 2 is very small at runtime. As a result, BACH 2 enables the verification of extremely large systems, as is demonstrated in our experiments. |

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.
