All know that most of the optimization of economic system can be converted into conditional extreme value problem which takes nonlinear operator or multi operator as constraints.

许多经济系统中的优化问题，可化为用单值非线性算子或多值算子形成约束条件的条件极值问题。

On the other hand, it can be used within a parenthesized expression or within the second expression of a conditional operator in such contexts.

另一方面，它可以使用在一个带括号的表达式或在第二个表达式在这样的环境条件操作符。
