Étoré, Pierre; Martinez, Miguel Exact simulation for solutions of one-dimensional stochastic differential equations with discontinuous drift. (English) Zbl 1315.65008 ESAIM, Probab. Stat. 18, 686-702 (2014). This paper proposes an exact simulation algorithm for the solution of a scalar unit additive system of stochastic differential equations in which the deterministic function is smooth apart from a discontinuity at \(0\). The approach is based on considering the convergence of a series of solutions to a skew perturbed additive noise problem in which the solutions converge to a limit algorithm of an exact simulation algorithm and extending it to the problem considered here. The exact simulation algorithm is based on building a skeleton with appropriate rejection procedure. Some simple simulations illustrate the approach.
