目标函数f(x)就是用设计变量来表示的所追求的目标形式，所以目标函数就

The objective function f (x) is the form of the objective pursued by the design variable, so the objective function is the function of the design variable, which is a scalar. In terms of engineering significance, the objective function is the performance standard of the system, such as the lightest weight, the lowest cost, and the most reasonable form of a structure; the shortest production time and energy consumption of a product; the best formula for an experiment, etc. The process of establishing the objective function is to find the relationship between the design variable and the target. The relationship between the objective function and the design variable can be represented by a curve, a curved surface, or a hypersurface.

The target function f(x) is the desired target form represented by the design variable, so the target function is the function of the design variable, is a scalar. In engineering sense, the target function is the performance standard of the system, for example, the lightest weight, minimum cost, most reasonable form of a structure, the shortest production time and minimum energy consumption of a product, the best formula of an experiment, etc., the process of establishing the target function is the process of finding the relationship between the design variable and the target, the relationship between the target function and the design variable can be represented by curve, surface or supersurface.

The objective function f (x) is the objective form which is expressed by the design variable, so the objective function is the function of the design variable, which is a scalar. In engineering sense, the objective function is the performance standard of the system, for example, the lightest weight, the lowest cost and the most reasonable form of a structure; the shortest production time and the smallest energy consumption of a product; the best formula of an experiment, etc. the process of establishing the objective function is the process of finding the relationship between the design variable and the objective, and the relationship between the objective function and the design variable is available A curve, surface, or hypersurface representation.<br>
