On the exact and $\varepsilon$-strong simulation of (jump) diffusions

Abstract: This paper introduces a framework for simulating finite dimensional representations of (jump) diffusion sample paths over finite intervals, without discretisation error (exactly), in such a way that the sample path can be restored at any finite collection of time points. Within this framework we extend existing exact algorithms and introduce novel adaptive approaches. We consider an application of the methodology developed within this paper which allows the simulation of upper and lower bounding processes whic… Show more

“…, Ξ K is a research topic in its own right, as it involves simulating a stopped diffusion process. We do not discuss this further, rather we refer the reader to literature on this topic; see for instance Beskos et al (2006) and Pollock et al (2013). The velocity field v 2 (s) in (26) is defined as the weighted average of the values of v H 2 (·) at the grid locations closest to s. The velocity field v 1 (s)…”

“…Overview of the exact algorithm. Here we give a brief overview of the exact algorithm (EA) of Beskos and Roberts (2005), Roberts (2006, 2008), and Pollock, Johansen and Roberts (2016), and we refer the reader to those papers for further details. The EA returns a recipe for simulating the sample paths of a diffusion X = (X t ) t∈[0,T ] satisfying the sde…”
