许多复杂的系统都可以用简单的主动步行者模型统一描述。这些复杂系统的例子有河流形成、热寻的导弹的运动、蚁群、蠕虫运动、聚合物爬行、视网膜神经元和血管、电沉积和介电击穿模式、软材料中的渗透、玻璃中的离子传输、粗糙表面、生物进化、种群动力学等。在主动步行者模型（AWM）中，步行者在其行走时改变景观，并且其脚步受到变化的景观的影响。本文综述了AWM的研究进展，并提出了一些新的研究成果。特别是，三个重要领域的应用AWM-轨道模式，内在的异常增长，粗糙表面-进行了讨论。
Many complex systems can be described in a unified way by the simple model of active walker(s). Examples of these complex systems are river formation, movement of heat-seeking missiles, ant swarms, worm movements, polymer reptation, retinal neurons and vessels, electrodeposit and dielectric breakdown patterns, percolation in soft materials, ion transport in glasses, rough surfaces, biological evolution, population dynamics, etc. In an active walker model (AWM), the walker changes the landscape as it walks and its steps are influenced by the changing landscape. In this paper, developments of the AWM are summarized and new results are presented. In particular, the three important areas of application of the AWM-- track patterns, intrinsic abnormal growth, and rough surfaces--are discussed.
