Efficiency of rejection-free dynamic Monte Carlo methods for homogeneous spin models, hard disk systems, and hard sphere systems

We construct asymptotic arguments for the relative efficiency of rejection-free Monte Carlo (MC) methods compared to the standard MC method. We find that the efficiency is proportional to exp(constβ) in the Ising, √β in the classical XY, and βin the classical Heisenberg spin systems with inverse temperature β, regardless of the dimension. The efficiency in hard particle systems is also obtained, and found to be proportional to (ρ_{cp} −ρ)^{−d} with the closest packing density ρ_{cp}, density ρ, and dimension d of the systems. We construct and implement a rejection-free Monte Carlo method for the hard-disk system. The RFMC has a greater computational efficiency at high densities, and the density dependence of the efficiency is as predicted by our arguments.journal articl

Finding Code-Clone Snippets in Large Source-Code Collection by ccgrep

Finding the same or similar code snippets in the source code for a query code snippet is one of the fundamental activities in software maintenance. Code clone detectors detect the same or similar code snippets, but they report all of the code clone pairs in the target, which are generally excessive to the users. In this paper, we propose ccgrep, a token-based pattern matching tool with the notion of code clone pairs. The user simply inputs a code snippet as a query and specifies the target source code, and gets the matched code snippets as the result. The query and the result snippets form clone pairs. The use of special tokens (named meta-tokens) in the query allows the user to have precise control over the matching. It works for the source code in C, C++, Java, and Python on Windows or Unix with practical scalability and performance. The evaluation results show that ccgrep is effective in finding intended code snippets in large Open Source Software.conference pape
