WebHigher order integrators require progressively more substeps. Yoshida (1990) gives examples of sixth- and eighth-order integrators using 14 and 30 substeps, respectively. WebWe introduce a time-integrator to sample with high order of accuracy the invariant distribution for a class of semilinear stochastic PDEs (SPDEs) driven by an additive space-time noise. Combined with a postprocessor, the new method is a modification with negligible overhead of the standard linearized implicit Euler--Maruyama method.
