拟凸函数(Quasiconvex functions) 拟凸这节写的不是特别完善,挖坑以后填了。 如果一个函数的下水平集是凸的,那么就称这个函数是拟凸的。 S_{\alpha}=\{x \in \operatorname{dom} f \mid f(x) \leq \alpha\} \;\text{ convex} \Longleftrightarrow f \;\text{ quasiconvex}\\ ...

Convex functions on non-convex domains 来自 dx.doi.org 喜欢 0 阅读量: 78 作者:HJM Peters,PP Wakker 摘要: It is shown that a convex function, defined on an arbitrary, possibly finite, subset of a linear space, can be extended to the whole space. An application to decision making under ...
A nonconvex surface What if the surface is non-convex? Well as you can see throwing a marble randomly onto the surface has very few chances of hitting the global minimum. Instead, it is likely that the marble will fall into one of the many local minima. And when this is the case, wh...
