Randomized Method of Subspace Corrections
Xiaozhe Hu, Jinchao Xu, Ludmil Zikatanov
In this paper, we consider the iterative method of subspace corrections with random ordering. We prove identities for the expected convergence rate, which can provide sharp estimat…
Optimal spatial-dynamic management to minimize the damages caused by aquatic invasive species
Katherine Y. Zipp, Yangqingxiang Wu, Kaiyi Wu +1
Invasive species have been recognized as a leading threat to biodiversity. In particular, lakes are especially affected by species invasions because they are closed systems sensiti…
An Adaptive Multigrid Method Based on Path Cover
Xiaozhe Hu, Junyuan Lin, Ludmil T. Zikatanov
We propose a path cover adaptive algebraic multigrid (PC-AMG) method for solving linear systems of weighted graph Laplacians and can also be applied to discretized second order…
