中文说明：优化是指以最小化或最大化某些函数取得最好的结果。大部分的工程活动，其目的可能是减低生产效率最大化或利润最大化。例如减轻飞机重量，确定空间飞行器的最优轨迹、 推土机、 风机、 泵的设计、 控制、 调度、 运行优化、 控制发电厂及电力系统控制等。优化算法分为两个主要类别常规优化算法和进化优化算法。传统的优化算法可分为线性编程方法，非线性的基础方法，可分离编程基于的方法和混合的整数规划基于的方法。
English Description：
Optimization means obtaining best results by minimizing or maximizing a certain function. In most of the engineering activities the objective could be minimize the production or maximize the efficiency or maximize the profit. For example minimize the aircraft weight, determining the optimal trajectory of space vehicles, designing of bulldozers, turbines, pumps, controlling, scheduling, optimal operation, control of power plants and control power system etc. Optimization algorithms are classified into two main categories conventional optimization algorithms and evolutionary optimization algorithm. Conventional optimization algorithms are classified into linear programming based method, non-linear based methods, separable programming based methods and mixed integer programming based methods.
