CALCULATING DEVICE FOR CALCULATING REACTION RATE CONSTANT

摘要

PROBLEM TO BE SOLVED: To provide a calculating device precisely and easily calculating a reaction rate constant, a method of controlling the calculating device, a program, and a computer-readable recording medium for recording the program.;SOLUTION: The calculating device 1 includes: a GA processing section 34 for updating an estimation value of a reaction rate constant of each reaction by a genetic algorithm to reduce an evaluation value indicating the degree of an error in the estimation value; an error calculation section 32 for calculating a difference between the concentration of each substance calculated by substituting an estimation value updated by the GA processing section 34 for a reaction rate formula and an actually measured concentration measured for each substance in advance to calculate the evaluation value from the calculated difference; an error evaluation section 33 for allowing the GA processing section 34 to update the estimation value when the evaluation value calculated by the error calculation section 32 is larger than a predetermined threshold; and a steepest gradient method processing section 35 for further updating the estimation value by the steepest gradient method when the evaluation value calculated by the error calculation section 32 is not more than the threshold, and determining the updated value as a reaction rate constant of each reaction. As a result, a precise reaction rate constant can be calculated easily.;COPYRIGHT: (C)2011,JPO&INPIT
