Title:
OPTIMUM SOLUTION CALCULATION METHOD, DEVICE, AND PROGRAM
Document Type and Number:
Japanese Patent JP2022168521
Kind Code:
A
Abstract:
To provide an optimum solution calculation method that finds an optimum solution stably and at high speed.SOLUTION: A calculation method for an optimum solution comprises: a first step for finding a solution where a linear approximation of an object function in a certain internal variable satisfies a target value; a second step for setting, when an object function value corresponding to the solution is less than the object function value of the first step, the solution as an internal variable to which the first step should be performed next; a third step for repeating, when the object function value corresponding to the solution is greater than or equal to the object function value of the first step, a change to bring the target value closer to the object function value corresponding to the internal variable and a calculation of the solution based on the linearly approximated function and a changed target value; a fourth step of setting, when the object function value corresponding to the solution by the third step is less than the object function value of the first step, the solution as an internal variable to which the first step should be performed next; and a fifth step for determining the optimum solution from the internal variable set in the second or fourth step.SELECTED DRAWING: Figure 19
