PROBLEM TO BE SOLVED: To provide a best condition searching device capable of searching for an optimum solution regardless of the scale of a search object, and to provided a system loss reducing device which minimizes effective power loss of the entire system.SOLUTION: The best condition searching device includes a memory 100 which stores an initial condition of system configuration as a current condition, a transition list 202 including an evaluation value corresponding to an effective power loss and the number of possible transitions for each section, an evaluation object selecting part 203 for selecting a section of high evaluation value at high probability, an adjacent condition selecting part 204 which selects and shifts an adjacent condition based on probability for a selected section, and an evaluation part 205 which determines the adjacent condition as the best condition so long as the entire evaluation value of entire system is minimum based on the evaluation value for each section constituting the adjacent condition after transition. A plurality of searching processes for the best condition by the evaluation object selecting part 203, the adjacent condition selecting part 204, and the evaluation part 205 are performed in parallel up to a forced transition frequency. These processes are repeated with a convergence determination frequency while replacing a current condition with the best condition. |
