Finally, the tumor cells of the system and its disorder were controlled using the adaptive control technique, and a stable and regular system was obtained. %K Discrete Tumor-Immune Model %K Fixed Points %K Stability %K Lyapunov Exponent %K Dissipative %K Neimark-Sacker Bifurcation %K Adaptive Control %U http://www.oalib.com/paper/6785874
