| Research Abstract |
Complex spin models were studied by new Monte Carlo algorithms. The generalized XY model was shown to be of Kosterlitz-Thouless type regardless of the parameter. The Monte Carlo method was also applied to the problem of image segmentationproblems, and it was shown that this method is effective especially combined with the graph-cut method. Moreover, the graphic processing unit (GPU) was successfully applied to the high-speed calculation of Monte Carlo simulation.
