Abstract:
1. A method for optimizing a network containing a plurality of nodes, the method comprising: inputting a network condition at each of plural timings in advance, the network condition being dependent on a number of nodes contained in the network and a type of each node contained in the network; accepting options of different restricting conditions concerning respective costs at each of the plural timings; designing, using a processor, a network satisfying a restricting condition accepted in the accepting under the network condition input in the inputting; outputting a design result of the designing; determining a maximum value of a variation of a total cost difference in the output design for each period between the plural timings; comparing the determined maximum value in the output design with a maximum value of a variation of a total cost difference in a previous design; and when the maximum value in the output design is less than the maximum value in the previous design, adopting the output design for the network.
