金融行情中的非函数问题
在数学中，非线性规划是求解由一系列未知实函数组成的组方程和不等式（统称为约束）定义的优化问题，伴随着一个要被最大化或最小化的目标函数，只是一些约束或目标函数是非线性的。它是最优化处理非线性问题的一个子领域。
Some simple data analysis, such as fitting the sum of peaks with known position and shape but unknown magnitude, can be done using linear methods, but generally these problems are also nonlinear. Typically, the theoretical model of a system with variable parameters and the experimental model with unknown parameters are studied. Numerical methods can be used to find the optimal values. In this case, in addition to the optimal values themselves, the accuracy of the results usually needs to be measured.
The nature of the constraint set has several possibilities, also known as the feasible region or feasible domain.
An infeasible problem refers to a situation where there is no set of variables that can satisfy all the constraints, meaning there are contradictory constraints, and no solution exists.
A feasible problem refers to a situation where at least one set of variables can satisfy all the constraints.
