The condition of the existence of solution of functional extremevalueproblem applied to maximum thrust nozzle is also presented.
同时，还导出了最大推力喷管这个泛函极值问题解存在的条件。

All know that most of the optimization of economic system can be converted into conditional extremevalueproblem 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。

The ordinary optimization algorithm can not solve the multi-extremevalueproblem in data assimilation, so an improvement to steepest descent algorithm is proposed to solve the problem.
