用户审美选择生成会动的类生命体，探索无规则系统中的智能表象
Limbomorphs
- 通过用户审美筛选时空场基因，生成三秒循环的类生命形态
- 不同扰动下表现出物种特异性反应，类似导航行为但非显式设计
- 揭示无明确规则系统中也能涌现类代理动态，适合对生成艺术与自组织感兴趣者
人工生命系统通常由环境、代理或两者之间的动态规则定义，由此可涌现出类生命模式。Gifbreeder 是 Picbreeder 的动画交互式进化计算平台，最初用于生成视觉艺术。不同于传统编码代理或环境，Gifbreeder 的基因编码时空场，并通过用户的审美选择进行演化。演化出的表现形式有时会呈现出具有运动能力的类生命体，我们称之为 Limbomorphs，因其存在于一个确定性的三秒循环‘滞留’状态中。我们通过输入空间扰动评估其行为，发现不同种类对各类扰动有特异反应。讨论这些反应是否反映目标导向行为（如导航），或仅是外观上的模拟。更广泛地探讨：在没有显式定义代理、环境或互动规则的系统中，代理态动态如何涌现。
原文摘要 · Abstract (English)
Artificial life systems are typically defined by a set of dynamical rules over an environment, an agent, or both, from which lifelike patterns may emerge. Gifbreeder is an animated version of the interactive evolutionary computation (IEC) platform Picbreeder, and was initially created to generate visual art. Instead of encoding the agent or the environment, Gifbreeder genomes encode a spatiotemporal field and evolve through the user's aesthetic selection. The evolved expressions can sometimes resemble motile lifelike creatures that we term Limbomorphs, given that they exist in a deterministic three-second looping "limbo". We assess their behavior via input-space perturbations and find species-specific reactions to different kinds of perturbations. We discuss whether these reactions may reflect goal-directed behavior like navigation, or merely the appearance of it, and more broadly how agent-like dynamics may emerge in a system with no explicitly defined agent, environment, or interaction rules.
