| Abstract | The development process for new algorithms or data structures often begins with the analysis of benchmark results to identify the drawbacks of already existing implementations. Furthermore it ends with the comparison of old and new implementations by using one or more well established benchmark. But how relevant, reproducible, fair, verifiable and usable those benchmarks may be, they have certain drawbacks. On the one hand a new implementation may be biased to provide good results for a specific benchmark. On the other hand benchmarks are very general and often fail to identify the worst and best cases of a specific implementation. In this paper we present a new approach for the comparison of algorithms and data structures on the implementation level using code coverage. Our approach uses model checking and multi-objective evolutionary algorithms to create test cases with a high code coverage. It then executes each of the given implementations with each of the test cases in order to calculate a cross coverage. Using this it calculates a combined coverage and weighted performance where implementations, which are not fully covered by the test cases of the other implementations, are punished. These metrics can be used to compare the performance of several implementations on a much deeper level than traditional benchmarks and they incorporate worst, best and average cases in an equal manner. We demonstrate this approach by two example sets of algorithms and outline the next research steps required in this context along with the greatest risks and challenges. |

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.
