I should say that is for a function of two variables to try to decide whether a given critical point is a minimum, a maximum or a saddle point.
但这种办法并不普遍,只能用于二元函数,来判断是极小值点、极大值点还是鞍点。
We establish a Lagrange multiplier theorem for strict efficiency in convex settings and express strict points as saddle points of an appropriate Lagrangian function.
讨论凸多目标最优化问题的严有效解,建立了拉格朗日乘子定理,并把严有效解表示为一个适当的拉格朗日函数的鞍。
It is set up the equipment adjusted and has such function: flat and saddle stitching.
它设有校车调整装置,具有平订或骑马订功能。
