| Abstract | Mutation operators have been studied at length to determine which ones are the ``best" at some metric (for example creates the least equivalent mutants, creates hard-to-kill mutants, etc.). These studies though have focused on specific test suites, where the test inputs and oracles are fixed, which leads to results that are strongly influenced by the test suites and thus makes the conclusions potentially less general. In this paper we consider all test inputs and we assume we have no prior knowledge about the likelihood of any specific inputs. We will also show how varying the strength of the oracle have a big impact on the results. We only consider a few mutation operators (mostly relational), only a handful of programs to mutate (amenable to probabilistic symbolic execution), and only consider how likely it is that a mutant is killed. A core finding is that the likelihood of reaching the source line where the mutation is applied, is an important contributor to the likelihood of killing the mutant and when we control for this we can see which operators create mutations that are too easy versus very hard to kill. . |

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.
