Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：A 1.344-approximation algorithm for the vertex cover problem
顶点覆盖问题 1.344 近似算法
2023/12/11
We present an algorithm for the vertex cover problem by combining the LP relaxation and the random edge-reductions. The algorithm has the expected approximation ratio of 1.344.
Micro-local Analysis for the Metropolis Algorithm
Convergence rate algorithm random eigenvalues and eigenvectors

We prove sharp rates of convergence to stationarity for a simple case of the Metropolis algorithm: the placement of a single disc of radius h randomly into the
interval [−1 − h, 1 + h], w...

In this paper, we are concerned with the study of an implicit iterative algorithm involving
a hemicontractive mapping and a quasi-nonexpansive mapping. We approximate
the common fixed points of the ...
