Reviews: Competitive Gradient Descent

Overall, the reviewers appreciated the novelty and simplicity of the algorithm. The paper is also well written and the methods are well motivated. In terms of content for revision: The lack of discussion around Newton-style approximation and dropping of diagonal terms in the Jacobian was raised again the discussions (see updated reviews). Additionally, we also sought an expert reviewer during discussions. The additional reviewer included below: ---- Additional review: The paper proposes an interesting new method for solving games Min_x F(x,y) Min_y G(x,y) which is, in general, different from running online gradient descent on x and y in parallel, or other existing methods.
