1 前言人工智能作为一门交叉和前沿科学,经过40多年的发展历程,在工程技术领域内获得了广泛的应用。它的出现和发展,是人类对自然界从简单到复杂的认识规律发展的必然结果。对于简单的物理与化学过程,传统的方法是用数学模型加以描述,以微分方程作为表示系统精确理论的主要工具,补充系统的参数、初始和边界条件,从而产生描述系统行为的一般定理。但客观世界本身就是不严格的、不确定的和模糊的,生命现象、人的感知和经验以及复杂的物理化学过程都难以完全用数学定理加以描述,因而人们寻求能刻划复杂系统的定性概括的途径及
1 Introduction Artificial Intelligence as a cross-cutting and cutting-edge science, after 40 years of development history, in the field of engineering technology has been widely used. Its emergence and development are the inevitable result of the development of mankind’s understanding of nature from simple to complex. For simple physical and chemical processes, the traditional method is to use mathematical models to describe, to differential equations as the main tool to represent the exact theory of the system, to complement the system parameters, initial and boundary conditions, resulting in a general description of system behavior. However, the objective world itself is not strict, uncertain and vague, the phenomenon of life, human perception and experience, and complex physical and chemical processes are difficult to fully describe with mathematical theorem, so people seek to characterize the complex summary of the system The way and
