命的一个重要特征就是能够自我繁殖，也就是自我复制。那么，程序能自我复制么？更一般的，一个系统上的构形能自我复制么？答案是肯定的，早在60年代的时候，著名科学家Von Neumann就研究过能够自我复制的细胞自动机，并从理论上证明了它是可能的。后来，随着人工生命的兴起，科学界兴起了研究自我复制的细胞自动机的热潮。在这个程序中，你能看到Langton的自我复制圈、chou的自我复制程序还有Langton的蚂蚁细胞自动机等等。-fate of the important features is a self-propagation, which is self-reproduction. Well, the procedure should be self-replicating? More generally, a system configuration of the self-replication? The answer is yes, back in the 1960s, the famous scientist on the Von Neumann studied to self-replicating cellular automata, and theoretically proved that it is possible. Later, as the rise of artificial life, the scientific community was created in the study self-replicating cellular automata craze. In this process, you can see the self-replication Langton laps chou self-reproduction procedures also Langton's Ant Cellular Automata and so on.
