Scalable and accurate detection of code clones
Programming and Computer Software. 2016. Vol. 42. No. 1. P. 27–33.
A detailed description of a method for detection of code clones is described. This method is based on the semantic analysis of programs and on new algorithms that make it scalable without affecting its accuracy. The proposed method involves two phases. In the first phase, the program dependence graph (PDG) is constructed while the program is compiled. LLVM is used as the compilation infrastructure. In the second phase, similar subgraphs of maximum size that represent code clones are detected. Before starting the search for similar subgraphs, the PDG is divided into subgraphs that will be considered as potential clones of each other. To ensure scalability of the search for similar subgraphs, the composition of algorithms is used. The first algorithm checks that a pair of graphs cannot have similar subgraphs of the desired size; this is done in a linear amount of time. If this algorithm fails, another (approximate) algorithm is executed to find similar subgraphs of maximum size. After similar subgraphs have been found, the program code is additionally checked for the position of the code lines corresponding to the detected clone candidates. Tests showed that the developed tool is more accurate than similar tools, such as MOSS, CCFinder, and CloneDR. Results obtained for the projects Linux-2.6, Firefox Mozilla, LLVM/Clang, and OpenSSL are presented

We investigate the spatial overlap of successive spin configurations in Markov chain Monte Carlo simulations using the local Metropolis algorithm and the Svendsen-Wang and Wolff cluster algorithms. We examine the dynamics of these algorithms for two models in different universality classes: the Ising model and the Potts model with three components. The overlap of two ...

A collection of vectors in a real vector space is called a unimodular system if any of its maximal linearly independent subsets generates the same free abelian group. This notion is closely connected with totally unimodular matrices: rows or columns of a totally unimodular matrix form a unimodular system and the matrix of coefficients of ...

An important parameter of the transport and logistics task is the structural stability of the system to external influences. In modern literature, the concept of structural stability is defined in its own way for each individual task, as a result of which there are difficulties in applying the developed methods to new problems. The transport ...

This article is dedicated to designing of the transport and logistics systems with built-in resistance to structural failures. The sustainability indicators reflect the impact of the failure of one or several hubs (communication channels) upon working capacity of the already functioning system. In the process of designing the system, the sustainability indicators also provide opportunities ...

In this study, we analyze the dielectric function of high-Tc cuprates as a function of doping level, taking into account the full energy band dispersion within the CuO2 monolayer. In addition to the conventional two-dimensional (2D) gapless plasmon mode, our findings reveal the existence of three anomalous branches within the plasmon spectrum. Two of these branches ...

In OECD countries, Science, Technology and Innovation (STI) policies were seen as key aspects of coping with the Covid-19 pandemic. Now that the pandemic is over, identifying which policy mix portfolios characterised countries in terms of their non-Covid-19 related and Covid-19 specific STI policies fills a knowledge gap on changes in STI policies induced by ...
