Center node: "an extended stable marriage problem algorithm for clone detection"
  Abstract: Code cloning negatively affects industrial software and threatens intellectual property. This paper presents a novel approach to detecting clone d software by using a bijective matching technique. The proposed approach focuses on increasing the range of similarit y measures and thus enhancingthe precision of the detection. This is achieved by extending a well -known stable-marriage problem (SMP) and demonstrating how matches between code fragments of different files can be expressed.A prototype of the proposed approach is provided using a proper scenario, which shows a noticeable improvement in several features of clone detection such as scalability and accuracy.
