Complexity of Multiblock Convex-Concave Saddle-Point Problems with General Smooth Coupling

Nhat Trung Nguyen, Ivan Dorofeev, Irina Podlipnova +2

We study multiblock convex--concave saddle-point problems of the form , with separately charged partial-gradient oracles for all three objective c…

Smooth or Separable? Sparse Block Acceleration for Entropy-Regularized Linear Programs

Irina Podlipnova, Maxim Mashtaler, Artem Agafonov +2

We study entropy-regularized linear programs with sparse affine constraints and compare two exact dual representations induced by whether a redundant normalization constraint is re…
