Tree Polymatrix Games Are PPAD-Hard. [PDF]
, 2020 We prove that it is PPAD-hard to compute a Nash equilibrium in a tree polymatrix game with twenty actions per player. This is the first PPAD hardness result for a game with a constant number of actions per player where the interaction graph is acyclic. Along the way we show PPAD-hardness for finding an $ $-fixed point of a 2D LinearFIXP instance, when

HIGH DENSITY POROUS POLYETHYLENE FACIAL IMPLANTS (PPAD) IN OROFACIAL HARMONIZATION
Health and Society, 2023 This work constitutes a literature review that explores the significance of Orofacial Harmonization Procedures (OHP) utilizing High-Density Porous Polyethylene Facial Implants (HDPE) to enhance facial aesthetics, contouring, rejuvenation, and volume augmentation.

The Complexity of Gradient Descent: CLS = PPAD $\cap$ PLS [PDF]
Journal of the ACM, 2020 We study search problems that can be solved by performing Gradient Descent on a bounded convex polytopal domain and show that this class is equal to the intersection of two well-known classes: PPAD and PLS. As our main underlying technical contribution, we show that computing a Karush-Kuhn-Tucker (KKT) point of a continuously ...

2D-TUCKER Is PPAD-Complete [PDF]
, 2009 Tucker's lemma states that if we triangulate the unit disc centered at the origin and color the vertices with {1, ? 1,2, ? 2} in an antipodal way (if |z| = 1, then the sum of the colors of z and ? z is zero), then there must be an edge for which the sum of the colors of its endpoints is zero. But how hard is it to find such an edge? We show that if the

TLR2 Activation by Porphyromonas gingivalis Requires Both PPAD Activity and Fimbriae
Frontiers in Immunology, 2022 Porphyromonas gingivalis , a keystone oral pathogen implicated in development and progression of periodontitis, may also contribute to the pathogenicity of diseases such as arthritis, atherosclerosis, and Alzheimer’s. P.
