To deal with nondifferentiable interval-valued functions (IVFs) (not necessarily convex), we present the notion of Fréchet subdifferentiability or gH-Fréchet subdifferentiability. We explore its relationship with ...

This article introduces the concept of weak sharp minima for convex interval-valued functions. To solve constrained and unconstrained convex IOPs by WSM, we provide primal and dual characterizations of the set of WSM. The ...
