| Abstract | During the initial construction and subsequent maintenance of an application, duplication of functionality is common, whether intentional or otherwise. This replicated functionality, known as a code clone, has a diverse set of causes and can have moderate to severe adverse effects on a software project in a variety of ways. A code clone is defined as multiple code fragments that produce similar results when provided the same input. While there is an array of powerful clone detection tools, most suffer from a variety of drawbacks including, most importantly, the inability to accurately and reliably detect the more difficult clone types. This paper presents a new technique for detecting code clones based on concolic analysis, which uses a mixture of concrete and symbolic values to traverse a large and diverse portion of the source code. By performing concolic analysis on the targeted source code and then examining the holistic output for similarities, code clone candidates can be consistently identified. We found that concolic analysis was able to accurately and reliably discover all four types of code clones with an average precision of .8, recall of .91, F-score of .85 and an accuracy of .99. |

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.
