| Abstract | Constraint-Based Testing was introduced fifteen years ago, in the context of mutation testing [1], to generate test cases by using constraint solving techniques. In our previous work [2, 3], we built a constraint-based model for generating automatically test data that cover all the decisions of a C program. Constraints are solved by using classical deductive methods such as domain reduction over finite domains and complete labelling. However, we found that some constraint systems cannot be solved in a reasonable amount of time with these techniques. Hence, we started looking at constraint-based local search (CBLS), a framework introduced by Michel and Van Hentenryck [4], to speed up the test data generation process in constraint-based testing. CBLS is a generic paradigm that proposes to implement multiple local search techniques such as Hill-climbing and simulated annealing by using the high-level concepts of invariants and differentiable objects. Invariants are simple relations expressed over incremental variables that must be maintained under assignments of new values while differentiable objects are relations that can be queried to evaluate the effect of local moves. Their significance comes from the many algorithms that evaluate the effect of various moves before selecting the neighbor to visit. Unlike invariants, a differentiable object can be queried through an interface shown below to evaluate the effect of local moves such as assignments and swaps. |

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.
