The value function turns out to be continuous in the whole plane, and is even continuouslydifferentiable in the interiors of both right and left half planes.
说明了值函数在整个平面上是连续的,在左右两个半平面的内部还是连续可微的。

The traditional bi-level model formulation of these problems is transformed into a single-level continuouslydifferentiable problem using a marginal function approach.
