| Abstract(in English) | The function synthesis problem for an unknown system requires to produce an approximate function which satisfies the relationships of given input and output data sets of the system. This problem is essential for the proper control of the system. When the system has the non-linearity characteristics, this problem becomes very difficult where the number of combinations of variables, constants, and operators quickly increases the computational complexity. This paper presents three improved methods for the genetic programming algorithm which is one of the function synthesis methods. They are the gradual expansion of function trees, the constant optimization by a local search, and the partial structure fixation of function trees based on the characteristics of the target system. The performance evaluation through the two-spirals problem and the sunspot prediction problem shows the effectiveness of the proposed three methods. |
