A powerful algorithm which can optimize such a relationship via developing a mathematical relationship between model variables is urgently needed. In this paper, we explore the use of Genetic Programming (GP) to develop a software cost estimation model utilizing the effect of both the developed line of code and the used methodology during the development. An application of estimating the effort for some NASA software projects is introduced. The performance of the developed GP based model was tested and compared to known models in the literature. The developed GP model was able to provide valuable estimation capabilities compared to other models.}, }
