Claim One:
1. A non-transitory computer readable storage medium storing a program extracting a parameter for each of a plurality of elements of a model equation, wherein when the program is executed by a computer: the computer obtains an input-output response of a physical device, the computer sets an initial value of the parameter for each of a plurality of elements of the model equation, the computer modifies the initial value of the parameter for each of the plurality of elements of the model equation, the computer evaluates a difference between the input-output response of the physical device and an output result of the model equation to which the parameter is inputted, the computer determines whether the difference is smaller than a reference difference value, the computer resets an initial value of the parameter for each of the plurality of elements of the model equation N times, and the computer extracts the parameter which corresponds to a minimum difference between the input-output response of the physical device and the output result of the model equation to which the parameter is inputted after resetting the initial value of the parameter N times, wherein the physical device comprises a semiconductor element, wherein the initial value of the parameter for each of the plurality of elements of the model equation is assigned by a random number generator program, and wherein N is a positive integer, N≧1.
