优化技术是一种以数学为基础，用于求解各种工程问题优化解的应用技术。作为一个重要的科学分支，它一直受到人们的广泛重视，并在诸多工程领域得到迅速推广和应用，如系统控制、人工智能、模式识别、生产调度、VLSI技术和计算机工程等。鉴于实际工程问题的复杂性、约束性、非线性、多极小、建模困难等特点，寻求一种适合于大规模并行且具有智能特征的算法已成为有关学科的一个主要研究目标和引人注目的研究方向。 20世纪80年代以来，一些新颖的优化算法，如人工神经网络、混沌、遗传算法、进化。(Optimization technique is an application technique based on mathematics, which is used to solve the optimization problems of various engineering problems. As an important branch of science, it has been paid more and more attention, and has been rapidly popularized and applied in many engineering fields, such as system control, artificial intelligence, pattern recognition, production scheduling, VLSI technology and computer engineering, etc.. In view of the complexity, constraints, nonlinearity, multi minima and modeling difficulties of practical engineering problems, searching for a large-scale parallel and intelligent algorithm has become one of the main research objectives and attractive research directions. Since 1980s, some novel optimization algorithms, such as artificial neural network, chaos, genetic algorithms, evolutionary programming.)
