• W1575554793 abstract "It is well known that for solutions of semi-linear parabolic PDEs, there are equivalent probabilistic interpretations, which yields the so called nonlinear Feymman-Kac formula. By adopting such formula, we consider in this work a novel numerical approach for solutions of hyperbolic conservation laws. Our numerical method consists in efficiently computing the viscosity solutions of conservation laws. However, instead of solving the viscosity problem directly (which is difficult), we find its equivalent probabilistic solution by adopting the Feymman-Kac formula, which relies on solving the equivalent forward backward stochastic differential equations. It is noticed that such framework possesses the following advantages: (i) the viscosity parameter can be chosen sufficiently small (say $10^{-10}$); (ii) the computational procedure on each discretized time level can be textit{completely parallel}; (iii) the traditional CFL condition is dramatically weakened; (iv) one does not need to handle the transition layers and discertizations of derivatives. Thus, high accuracy viscosity solutions can be efficiently found. Several numerical examples are given to demonstrate the effectiveness of the proposed numerical method." @default.
