Abstract: One of the most critical diseases, which have a considerable mortality rate in the world, is coronary artery disease. To improve the diagnosis of this dangerous disease in the early stages, we proposed a system which uses data mining techniques and an evolutionary algorithm called imperialist competitive algorithm (ICA). Since the convergence speed is one of the important factors in an evolutionary algorithm, a change was made in this algorithm so that the convergence occurs more quickly. The results show that ICA and improved ICA produce the same results in classification accuracy, but the convergence time is different. To compare the efficiency of CA/improved ICA with another evolutionary algorithm, PSO algorithm used to test the proposed system. Results confirm the superiority of ICA in terms of accuracy and convergence speed to PSO in adjusting membership functions problem. The proposed system gets an accuracy of 94.92%, which is high in comparison to similar works.
