| Abstract(in English) | In traditional genetic programming (GP), the explosive growth of trees often occurs, and it requires an enormous amount of calculation. To conquer this difficulty, we consider fitness functions based on error and complexity terms. Although the fitness functions can restrain growth of tree, the balance of error and complexity terms is important to prevent excessive restraint of tree growth. In this paper, we present a new method dynamically balancing error and complexity terms. Our method is compared with the method already proposed by Zhang et al. The effectiveness of our method is shown by a computer simulation on symbolic regressions. |
