Computer simulation (sim for short) is a method of computer simulation. The simulator developed by computer software can perform complex simulation tasks, such as fault tree analysis and testing VLSI logic design. In the field of optimization, the simulation of physical processes is often used to optimize control strategies together with evolutionary computation. There is a special type of computer simulator: computer architecture simulator, which is used to simulate another computer with incompatible instructions or different systems on one computer. Alan turing once suggested that Machine A or Machine B (of different systems) can imitate each other with instructions in theory, which is not limited by hardware and speed. However, in reality, speed and hardware must be considered.
