报告摘要: I will give a brief introduction to our recent works regarding the applications of interacting particle systems in scientific computing. In the first part, I will talk about several algorithms we proposed for sampling and solving PDEs using interacting particle systems, which can be efficiently implemented with the random batch approximation. In particular, the random batch Monte Carlo method, the random batch Ewald method and a particle method for PNP equation will be talked about. The second part goes to the fluctuation suppression and enhancement phenomena in interacting particle systems, which may give some evidence why sampling based on particle systems may be preferred sometimes.
