Linearly Convergent Away-Step Conditional Gradient for Non-strongly Convex Functions
Amir Beck, Shimrit Shtern
We consider the problem of minimizing a function, which is the sum of a linear function and a composition of a strongly convex function with a linear transformation, over a compact…

The Cyclic Block Conditional Gradient Method for Convex Optimization Problems
Amir Beck, Edouard Pauwels, Shoham Sabach
In this paper we study the convex problem of optimizing the sum of a smooth function and a compactly supported non-smooth term with a specific separable form. We analyze the block…
