An Accelerated Inexact Proximal Point Method for Solving Nonconvex-Concave Min-Max Problems [PDF]
SIAM Journal on Optimization, 2019 This paper presents a quadratic-penalty type method for solving linearly-constrained composite nonconvex-concave min-max problems. The method consists of solving a sequence of penalty subproblems which, due to the min-max structure of the problem, are ...

Log-concave polynomials, I: Entropy and a deterministic approximation algorithm for counting bases of matroids [PDF]
Duke mathematical journal, 2018 We give a deterministic polynomial time $2^{O(r)}$-approximation algorithm for the number of bases of a given matroid of rank $r$ and the number of common bases of any two matroids of rank $r$.

The mathematical model of the precessional gear and the process of generation of inclined teeth [PDF]
Journal of Engineering Science (Chişinău), 2020 The paper deals with the development of precessional gears with toothed gearing with concave-concave contact of inclined teeth. In order to increase the bearing capacity and the mechanical efficiency of the precessional gear, the contact of the teeth is ...

Avoidance of Convex and Concave Obstacles With Convergence Ensured Through Contraction
IEEE Robotics and Automation Letters, 2019 This letter presents a closed-form approach to obstacle avoidance for multiple moving convex and star-shaped concave obstacles. The method takes inspiration in harmonic-potential fields. It inherits the convergence properties of harmonic potentials.

Test and Optimization of Oilseed Rape (Brassica napus L.) Threshing Device Based on DEM
Agriculture, 2022 Gridded concave plate sieves are usually used for threshing operations of grain and oilseed crops. In response to the problems of high threshing loss rate and grain breakage rate when threshing oilseed rape, this research modified the threshing concave ...

Mining reasonable distance of horizontal concave slope based on variable scale chaotic algorithms
Open Physics, 2020 Horizontal concave slope structure is a common mining structure. It is the basis of mining safety to grasp the reasonable mining distance of horizontal concave slope. Therefore, based on variable scale chaotic algorithm, the reasonable mining distance of

Log-Concave Polynomials III: Mason's Ultra-Log-Concavity Conjecture for Independent Sets of Matroids [PDF]
Proceedings of the American Mathematical Society, 2018 We give a self-contained proof of the strongest version of Mason’s conjecture, namely that for any matroid the sequence of the number of independent sets of given sizes is ultra log-concave.
