摘要:

本文表明,简单而重要的特点,共同进化可以发生在进化算法时,只有少数条件得到满足。我们发现,基于相互作用的适应度测量,如适应度(线性)排名允许一种形式的共同进化动力学,当1)在排名过程中能够相互作用的解决方案的变化和2)进化发生在多目标环境中时,可以观察到。这项研究至少在两个方面有助于模拟进化的研究。首先,它建立了一个更广泛的协同进化和多目标优化之间的关系比以前被认为是在文献中。其次,它表明共同进化行为的前提条件比以前认为的要弱。特别是,我们的模型表明,物种之间的直接合作或竞争是不需要共同进化的发生。此外,我们的实验提供的证据表明,环境扰动可以驱动共同进化过程,这一结论反映了双相进化理论中提出的论点。在讨论中,我们简要地考虑了我们的结果如何揭示这一点和其他最近的进化理论。

英文摘要:

This paper demonstrates that simple yet important characteristics of coevolution can occur in evolutionary algorithms when only a few conditions are met. We find that interaction-based fitness measurements such as fitness (linear) ranking allow for a form of coevolutionary dynamics that is observed when 1) changes are made in what solutions are able to interact during the ranking process and 2) evolution takes place in a multi-objective environment. This research contributes to the study of simulated evolution in a at least two ways. First, it establishes a broader relationship between coevolution and multi-objective optimization than has been previously considered in the literature. Second, it demonstrates that the preconditions for coevolutionary behavior are weaker than previously thought. In particular, our model indicates that direct cooperation or competition between species is not required for coevolution to take place. Moreover, our experiments provide evidence that environmental perturbations can drive coevolutionary processes; a conclusion that mirrors arguments put forth in dual phase evolution theory. In the discussion, we briefly consider how our results may shed light onto this and other recent theories of evolution.
