Monte carlo and quasi-monte carlo methods
RE Caflisch - Acta numerica, 1998 - cambridge.org
Monte Carlo is one of the most versatile and widely used numerical methods. Its
convergence rate, O (N− 1/2), is independent of dimension, which shows Monte Carlo to be …

A new asymptotic preserving scheme based on micro-macro formulation for linear kinetic equations in the diffusion limit
M Lemou, L Mieussens - SIAM Journal on Scientific Computing, 2008 - SIAM
We propose a new numerical scheme for linear transport equations. It is based on a
decomposition of the distribution function into equilibrium and nonequilibrium parts. We also …

Numerical schemes for hyperbolic conservation laws with stiff relaxation terms
S Jin, CD Levermore - Journal of computational physics, 1996 - Elsevier
Hyperbolic systems often have relaxation terms that give them a partially conservative form
and that lead to a long-time behavior governed by reduced systems that are parabolic in …
