Such method is based on the physical analogy, when temperature of system is cooled gradually, so the system will achieve its global minimum state. The method was used to minimize linearized Ginzburg-Landau functional. The optimum order parameters has been obtained through minimization process of the functional. Comparison with the other results researcher's finding showed that the result presented in the thesis are in line, eventhough a high accuracy has not been achieved yet. Keywords: simulated annealing, Ginzburg-Landau functional, critical field Hc3 date: 2004-01-01 date_type: published publication: SAINS DAN SIBERNATIKA volume: 17 number: 1 publisher: Program Pascasarjana Universitas Gadjah Mada pagerange: 143-156 refereed: TRUE issn: 1693-7392 referencetext: Cyrot, M. dan Pavuna, M. 1992.
